Vibration control matching

Insulation of periodically excited vibrationsThe effect of vibration insulation depends mainly on the ratio of the disturbance frequency or excitation frequency to the natural frequency of the insulator (matching ratio), and its damping.With source insulation the excitation frequency is the machinespeed or stroke rates, with receiver insulation disturbing ground vibrations. Generally it can be said that the lower the natural frequency of the insulator the better the efficiency of the insulator, i.e., the larger the ratio of disturbing frequency is compared to the natural frequency. The resulting graph showsthat an isolating effect only occurs when the value of the harmo- nizing ratio is greater than � 2 At smaller values an amplification(resonance magnification) of the disturbing force may also occur.

The transmission factortaking into account thedamping ratio D is:

VP

Disturbing or exciting frequency

Natural frequency of the insulator

Matching ratio

Usually a matching ratio of between 3 and 4 is striven for, whereby 3 is considered the technical lower limit and 4 the economic upper limit. A matching ratio larger than 4 cannot normally be justified from the economic perspective because the material expense would increase above average compared to the degree of insulation

2

IMPACT INSULATION

Matching ratio Ƞ

Impact insulationThe physical properties of impacts are their duration, direction and magnitude. The object of impact insulation is to change the forcing frequency consisting of a high kick into an impulse of longer duration accompanied by small residual forces. Different from periodically excited vibrations, the system provided with springs vibrates in the excited natural frequency of the insulated system, not according to its number of strokes. The residual forces transferred via the insulators become increasingly smaller, the longer the natural vibration period lasts and therefore the smaller the natural frequency of the system sitting on a foundation equipped with springs.So, the efficiency factor of an impact insulation is:

= natural frequency of the system rigidly secured to the ground= natural frequency of the system when placed on insulators containing springs.

Insulation padsBilz insulation pads have been used successfully for many years in a variety of indu-stries as an economical solution in the fight against problems caused by vibration andstructure-borne noise.Made from a precisely defined combination of nitrile rubber and cork particlesembedded in a composite of cotton fibres, the physical and mechanical properties ofthis high-quality composite material meet all of the current requirements for variousindustrial applications depending on type of pad. Very good damping properties ensureoptimum deflection and level consistency both under static and under dynamicloading.The material composition used ensures secure anti-slip protection on conventionalindustrial floors. It has high resistance properties particularly to modern coolinglubricants.

FOUR POSSIBLE OPTIONS FOR THE USE OF INSULATION PADS FOR MACHINE INSTALLATION

Avoiding vibration and structure-borne noise problems has alwaysbeen in our focus during the development of Bilz insulating pads.As, depending on the type of machine, the requirements can bevery different because of the dynamic particularities, there arenumerous different types of pads available for almost any vibra-tion problem. Especially noteworthy are the excellent compre-ssion set values of our insulation pads. This property is particularlyimportant in vibration-isolated mounting of modern machinesbecause the geometric accuracy must remain unchanged andstable for years.

Structure-borne noiseEffective noise insulation

Virtually unlimited service life with adherence to load values. Nopermanent changes in shape.

Aging resistant

Chemical resistanceExceptionally good resistance to oils, grease, acids and coolingemulsions used in industry.

Temperature resistance-20 °C to +120 °C

Damping propertiesVery high degree of damping of up to 30 %

Stable connection to themachine bed using bolt-oninstallation fittings thatremain in place when themachine is lifted. Specificallyfor machines with highdynamic forces (injectionmoulding machines,stamping equipment, etc.).

Free-standing machinefoundations using Bilz insula-tion pads with low demandson alignment. The unevenfloor is compensated for withpads, etc. The arrangementof the pads is usually apattern of points, not overthe full surface. Number andsize of the required insula-tion pads is given by theweight of the machine andthe existing support surface.

Bolt-through groundanchoring using insulationpads and insulation washers.The use of insulationwashers prevents vibrationsbeing transmitted throughthe bolt.

Highly effective shock andvibration insulation by Bilzinsulation pad sets.Different Bilz pads arecombined into pad setsoffering significantlyimproved insulation.

Bilz insulation pads are resistant to the following substances:

Lubricants

Greases for plain and roller bearings, gear greases

Synthetic lubricantsPolyalkylene, carboxylic acid esters, antifreezeCombustibles and fuelsPetrol, diesel fuel, heating oil, aviation fuel, special fuels

Mineral oils

Application

Advantages • Precise and accurate machine positioning and leveling. • No horizontal machine movement.

• Considerable reduction in machine maintenance cost. • No special foundation required.

• Machine accuracy maintained for longer duration. • Sufficient adjustment height.

• Reduced installation time thanks to effortless and precise leveling.

AMT Machine Fixator, Series MF

AMT MF series machine fixator is a one stop solution for precise yet cost efficient installation of heavy machinery and equipment. They are available in two basic designs: bolt-through and bolt-on. The "bolt-through" design has a clearance hole for an anchor bolt to securely anchor machines to the floor or foundation. The "bolt-on" design comes with fasteners and is designed for free-standing installations. MF series machine fixator is based on double wedge principle. Both wedges move towards or away from the loading center symmetrically. Equalizing these forces around the center results in an absolute rigid and stable anchoring system. As there is equal load distribution through two lifting wedges, the force required to raise or lower a machine is reduced considerably, resulting in effortless and precision leveling.

• Heavy machine tools for processing crankshafts and camshafts or rollers

• Boring machines, gear testing machines, horizontal and critical machining centers

• Surface grinding and laser cutting machines• Die-casting and plastic injection molding machines• Punching and press machines• Turbine and compressors• Printing machines

Precision levelling wedgesDue to their large contact area Bilz precision levelling wedges (PK) for vibration and structure-borne noise insulation offer optimum support and stiffening of the machine bed.They are available in a wide range of sizes and dimensions as free-standing, bolt-on to the machine or bolt-through to the foundation design.

The proven design principle enables the machine to be quickly leveled to a degree of leveling in the 1/100 mm (0.0004”) range even at loads of 100 tons per wedge.The powerful self-locking effect of the leveling bolt prevents self-loosening under the effects of vibration. Depending on the application, their use in conjunction with Bilz isolation pads creates the perfect rigidity with very effective vibration isolation.

On request we supply special solutions in terms of color, isolation pad mounting and dimension.

Allowable temperature range: -20 °C to +120 °C (-5 to +250 °F)

To simplify handling the upper or lower wedge can be secured with a tension spring.

The general tolerances in accordance with ISO 2768 vL apply to the specified lengths and widths. The specified height at the center position is subject to a tolerance of ± 1mm (±0.04").

FAEBI rubber air springs are used for thehighly effective insulation of machines, apparatus and aggregates from shocks, vibrations and structure borne noise. Theelement comprises of a bell-shaped rubberform made from high-grade elastomer witha reinforced side wall. The constructive design does not only achieve excellent insulation properties, but also very high mechanical stability. Damage due to over-load or a sudden pressure drop is virtuallyimpossible. The air spring element has avery low degree of deflection in the horizontal direction. The inclusion of anti-slip pads on the spring element baseplate means that additional floor anchoringis not usually required.

®

Note:

n FAEBI elements can also be suppliedin stainless steel designs and fromEDPM elastomer for outdoor use (suchas air conditioning).

®

n To reduce the movement amplitude inthe vertical direction the FAEBI- HDvariant is supplied with additionaldamping.

®

Applications

Perfectly suited for source insulation offast running presses, forging hammers andother machines and aggregates with highlydynamic disturbance forces. Passive insula-tion of measuring and test equipment aswell as highly accurate machine tools. Canalso be combined with mechanical levelcontrol on request.

SHOCK AND VIBRATION INSULATION

The natural frequency of the rubber airspring in the vertical direction is between3 and 14 Hz depending on the allowablestatic load and variant. The maximumspring deflection in response to a pulseload is up to 15mm depending on thetype and size of the air spring.

ADVANTAGES COMPARED TO STEEL SPRINGS

In comparison to steel springs the use of air spring offers manyadvantages when used for vibration insulation:

n Flexible insulation system design: Changes in the static or dynamic loads can be compensatedfor by adjusting the air pressure. This can be performed eithermanually or pneumatically (e.g. using Bilz level control)

n Integrated damping, therefore separate damping is not necessary.

n No transmission of structure borne noise

Material: Steel sheet (primed black) The protective cover is also available in stainless steel on request.

® ®PROTECTIVE COVERFOR FAEBI AND FAEBI -HD ELEMENTS

® ®If the surface of the FAEBI element (see Type series FAEBI or ® FAEBI -HD) is not completely covered by the bottom edge of

the machine, then an appropriate hood is required to ensure the sufficient load distribution across the air spring.A hood will also provide protection from external damage.

Type series FAEBI® -HD with adjustable damping

The combined rubber-air spring insulator FAEBI -HD with adjustable damping comprises of an elastomer metal bonding with reinforced side wall and a two-chamber system. To achieve the greatest possible damping effect the interior of theair spring is divided into two air chambers connected by an airhose (load and damping volume). An adjustable throttle valve isused to set the flow cross section to the desired damping effectfrom the outside. The significantly higher damping effect compared to a single chamber system (FAEBI ) reduces the resonance amplification substantially and the machine movementsfade noticeably faster. The increased energy substancially absorp-tion also has a positive effect on the manufactured goods and onmachine and tool wear.

®

®

Benefits:In comparison to viscous damping air damping is absolutely free of wear and maintenance-free and the damping factor can be easily adjusted from outside.

Note

n Ensure that the element is selected so that the maximum load(static and dynamic load) is not exceeded! For applicationswith higher dynamics harder variants of the FAEBI reduce thedeflection of the element. However, the softer the element is,the better the achievable insulation effect is. Please contactus, we are happy to assist with selecting a suitable element.

®

n If the bottom edge of the machine does not completely coverØD, we recommend the use of our special protective cover


n The elements are attached to the holes provided on the machine using the bolts supplied Anchoring tothe floor is usually not necessary.

n Bolt in the bolt by hand only, do not use an open-endwrench. Also only tighten the nut with low torque.

n The machine is placed on the deflated element, which is theninflated in stages using the standard valve until dimension H(= working height) is reached. The maximum specified airpressure must also not be exceeded!

n Inflation and deflation may only take place under load, observe the maximum permissible pressure.

n Up to +/- 5 mm are available for levelling.

FAEBI ® MPN-LCV

The mechanical-pneumatic level control (MPN) with our robustproportional valve LVC represents a simple but effective solutionfor preventing skew positions resulting from load changes. A plunger continuously probes the level and the position of theplunger is transmitted to a slide valve. The air spring is eitherpressurized or the internal pressure is vented in accordance withthe position of the plunger. The adjustable target level is maintained within an accuracy of ± 1/10 mm. In principle three control valves are used, that optionally have anupstream air maintenance unit for conditioning the pneumatic airsupply, limiting the system pressure to 6 bar, removing accumu-lated condensate and filtering out solid particles (rust and dust).

Advantages compared to conventional steel springs®The use of Bilz BiAir air spring insulators with active level

control constantly maintains the correct level of machines orfoundations. The level control and adjustment is completelyautomatic! The pressure in the air springs is appropriately adjusted by in-or deflating in response to load changes. This keeps the insulating effect constant in every case. Unlike steel springs air springs do not transmit structure-bornesound.

®The BiAir membrane air spring insulator is made of turned orcast aluminium. The air space is enclosed by a thin-walled flexibleand pressure-resistant rolling membrane. A piston sits on top ofthe membrane and is pressed into the air space.

This design allows a highly-effective insulation against vibration. In order to simultaneously achieve a high degree of damping, the air space within the insulator is divided into two chambers connectedwith an air tube (load/damping volume). An adjustable throttlevalve is used to set the flow cross section to the desired dampingeffect from the outside. The friction in the air flow generated bythe throttle valve can create a damping effect of up to 15 %.

Damage to the rolling membrane due to overpressure is virtuallyexcluded through the use of additional safety valves or a mechan-ical piston stroke limit.

MPN Mechanical pneumatic levelcontrol for Bilz air springs

Bilz mechanical pneumatic level control for air spring systems ® ® ®with FAEBI and FAEBI -HD rubber or BiAir membrane air springs.

Powerful vibration insulation at very high level consistency.

32

MPN-LCV MPN-PVM

Mechanical pneumatic level control MPNBilz level control systems are significant components in the

®optimum function of vibration insulation using FAEBI and® ®FAEBI -HD rubber or BiAir membrane air springs. They prevent

impermissible and undesired deflection of the insulators or an out-of-level condition of the machine that can be caused by load changes on an air spring mounted machine or system.Rapidly adding or venting air enables the air pressure within the air spring to be matched to the respective load, automati-cally controlling the height of the individual air springs. This enables the highest degree of stability and effective insulationeven with changes in the centre of gravity.

Valve functions

The level is continuously sensed using the plunger. The position of the plunger is directly applied to the slide valveand the air spring is either pressurized or vented. The target levelis adjusted by turning the knurled adjustment ring. The heightand level of the machine is adjusted using three valves.

Design

At least three air springs are controlled (Fig. 1). If more insulators are required due to reasons of design or load, the systemmust still be worked in three controlled groups, as otherwisethe system is statically overdetermined. This is achieved byusing multiple insulators in parallel as a group (Fig.2). An additional air maintenance unit is installed upstream of the control valves to prepare the compressed air.

FOUNDATION INSULATION

Your benefits from Bilz foundation insulations:

Indirect vibration insulation of a machine or system enhances thenatural rigidity and leads to a significant improvement of the dynamic behaviour in response to large changes in load and traveldistances. The exact design of the foundation according to the machine properties ensures an economic solution for the long-term and trouble-free operation of the system.

We have many years and a wide range of experience in the design and projecting of machine foundations. We therefore offer all of thenecessary services from single source:

n The increased machine rigidity enables effective vibra-tion insulation even with large machines and systems.This results in increased precision, receiver insulationand protects the machine surroundings.

n Reduction of the vibration amplitude by adding additional mass or moment of inertia and lowering ofthe centre of gravity. This results in electronic compo-nents, control, bearings, etc., enduring less stress andthe quality of the results are significantly improved, in particular for applications where the level is critical.

n Smaller relative movements of individual machine components or attachments (such as robots, materialfeeds, etc.)

n Reduction of the size of the foundation compared to thefoundation design without vibration insulation.

n All-round service from one single source; fewer interfaces and contacts.

Direct insulation means that vibrationinsulators are fitted directly under orin the machine, usually at the same locations as the available installationpoints. Direct insulation requires that the machine bed or base frame has sufficient intrinsic rigidity and that itwill not warp or twist due to elasticmounting. In addition the machinegeometry must allow the suitablearrangement of the insulators.

Depending onn Machine dimensions, n Machine centre of gravity, n Dynamic forces acting on the machine,n Permissible machine movement,n Requirements on the insulation,n Mobility (flexible installation site),n Attachment parts or feeds,n Type of installation site

(for example permissible floor loading, installation in above groundfloors of a building),

This is achieved either by providing ablock foundation made of concrete a steel platform or a cast plate. In this case the insulation isreferred to as indirect insulation.

DIRECT INSULATION INDIRECT INSULATION

Machines whose intrinsic rigidity is notsufficient for direct insulation require arigidly designed intermediate construc-tion to be fitted between the insulatorsand the machine. This method also allows the positioning of the insulators to be optimised for the application.

Vibration foundation with insulations pad sets Multiple layering of Bilz insulation pads can achieve significantly reduced naturalfrequencies and therefore considerably increase the insulation effect compared with asingle layer of insulation pads.

These pad sets are particularly suitable for large machines and sprung foundations.The vibration insulation and damping properties of these insulation pads remainunchanged even after years of dynamic loading.

Bilz insulation pads are resistant against the most common greases, oils, coolants,cleaning agents as well as acids and alkalis.

Insulation pad sets

Effective insulation pads for highly dynamic machines andfoundations.

The permissible load capacity of a pad lies between 5 and240 Kg/cm depending on the application. The number and size

of the insulating layers and the required distribution of thepad sets is determined specifically for the application by Bilz.

Vibration Insulation Platforms & Test Beds

Basic platform Platform for minimum installation heightand for systems with a very high centre of gravity

Platform for low installation height and forsystems with a high centre of gravity

Many applications require indirect insulation due to the require-ments for effective insulation and level control or due to insuffi-cient intrinsic rigidity. If foundation insulation is not possible ase.g.

n installation is on the elevated floors of a building,

n the site of installation is of restricted space,

n the site of installation should be flexible (mobility),

then mounting the machine to a vibration insulated platform is a proven solution.

Usually either welded steel constructions or cast plates are used.Depending on the design of the platform the base of the machineis additionally extended and the centre of gravity is lowered byadding mass or the position of the insulators, which significantlyenhances the stability of the overall system. In this way machineswith a high centre of gravity and/or small base area can also bemounted to very low frequency and therefore soft insulators.

Measurement and Vibration AnalysisMeasurement of vibrations and shocks using state of the art instruments –FFT Analyser and analysis software

Due to our decades of experience in the fieldof vibration technology and isolation, weguarantee you technically and economicallyreliable problem solutions. The on site measurement and analysis of vibration emissions and immissions is an essential partof our consulting services with regard to vibration and vibration insulation. Based onthe measurement results, we develop vibration technical measures to comply withlegally prescribed limits.

The assessment of periodic and non-periodicvibrations in the frequency range from 1 Hzto 80 Hz is e.g. based on the DIN 4150 “Vibrations in buildings; Effects on persons inbuildings”. Requirements and reference values are stated herein, in general the considerable disturbance of people in domestic properties and similar premises isto be avoided in order to comply with theseregulations.

Procedure

In the first step the maximum value of the vibration levels for the three directional components x, y and z are determined.The largest of these three values KBF maxis compared with the reference values A uand Ao according to Table 1

n If KBFmax is less than or equal to the(lower) reference value of A u, then the requirements of this standard are met.

n If KBFmax is more than the (upper) refer-ence value of A u, then the requirements of this standard are not met.

n For short-term impacts and those that donot occur often, the requirement of thestandard is met if KBF max is less than orequal to Ao.

Another current example of the requirementfor a vibration analysis is the storage of high-precision 3D-measurement machines, as wellas other testing, measuring or grinding machines. Typically measurements must becarried out by such machines at the plannedsite, to ensure that existing ground vibrationsdo not exceed the permitted values (see Chart1). To do this, the vibration acceleration is

determined within a given frequency spectrum (1–100 Hz), as a simple sum valuemeasurement would provide insufficient information about the exact environmentalconditions. The analysis of the accelerationtime signals is carried out using a fast-fourier-analyser, which indicates the correspondingmeasurement value (vibration acceleration ing) for each frequency of the spectrum. If thedisturbances (vibration interference) are outof the permissible range, the appropriate insulation can be determined with the help of our PC calculation program.

Very accurate vibration analysis in the lowerfrequency range are carried out with highlysensitive Geophones. Vibration speeds frombelow 0.01 µm/s in the range from 0.2 to30 Hz can be recorded with the Geophones.Extremely precise measurements of vibrationare necessary for an optimal and customer-specific design, particularly in the semicon-ductor and Nanotech industry as well as forhigh-precision 3D-measurement machines.
