m1000 Hz High-Cycle FatigueTest System
MTS has developed a servohydraulic testsystem for accurate and reliable fatiguetesting at 1000 Hz. The system is alreadybeing used by several laboratories fortesting materials used in advanced aero-space applications.High cycle fatigue testing to long lives
requires high-frequency equipment. A109 cycle test would require more thanseven months with a traditional 50 Hzservohydraulic testing machine. Thesame test takes only 11 days with the1,000 Hz high-cycle fatigue test system.
The 1000 Hz high-cycle fatigue testsystem maintains high waveform fidelitywhile running at high frequency. It allowshighly accurate control with a static loadcapacity of ±25 kN (±5.5 kip). Environ-mental chambers and induction heat(available as system options) allow thesystem to be used for determining tem-perature effects during fatigue testing.
System Benefits�Uniaxial system, static capacity ±25 kN (±5.5 kip)*
�Total displacement ±25.4 mm (±1in)
�Able to perform 1 billion cycletest in 11 days
�High mechanical durabilityachieved through Voice CoilServovalve technology
�AdapTrac™ amplitude phasecontrol (APC) softwareincreases the effective fre-quency range for 1,000 Hz sustained testing
The MTS 1000 Hz High-Cycle Fatigue Test System
* Dynamic performance depen-dent upon specimen material,configuration, and grip mass.
