What can we get in CAE ?

Computer Aided Engineering (CAE) software.

• Used in finite element analysis (FEA) is suitable for solving complex problems.

•Analysis the situation and Solve problems : Stresses, Strains,Displacement, Deformation , Heat transfer, Optimization…...

Finite Element Analysis (FEA)

Finite Element Analysis can powerfully to solve:

•Complex shapes,

•Different structural components connect together (beams, solids and shells)

•Structures composed of various materials.

Finite Element Analysis (FEA)

“Accurstress’ function to create finite element:

•Automatically create the small finite element for the very small area or faces

•Fast to get the accuracy result

SRAC 2001

Application of Cosmos/Works

•Static Analysis

•Contact Stress Analysis

•Frequency Analysis

•Buckling Analysis

•Thermal Analysis

•Optimization Analysis

SRAC 2001

Advantage of Cosmos/Works

•Operation with SolidWorks directly

•Create Web Report automatically

•User friendly (easy to use)

•Reduce: Design Cycle, Manufacturing Cost, Product Cost & Engineers

calculation time.

SRAC 2001

Application of Cosmos/Motion

•Displacement , Velocities, & Acceleration plots

•Trace Paths

•3D contact

•Review reaction Forces

•Export to FEA, ADAMS

•Optimization Analysis

How does COSMOS/Motion Fit into Virtual Testing

Determine if a design is going to work before a physical prototype is made or tested. Save time in design & development Evaluate many more ideas than you can physically Save money in testing Makes FEA more accurate. Reduces Tooling Modification costs. Get products to market quicker Reduce product failures, Reduce warranty costs

How does COSMOS/Motion Fit into Virtual Testing

Physics Based Motion Simulation Communicate ideas/information about mechanisms Determine how the mechanism will move. Find Clearance/Interference through entire range of motion Create Animations as .AVI and VRML files Will the mechanism work…for sure? Analyze the engineering data behind the motion Determine how forces effect the mechanism Determine reaction forces, loads, torques, accelerations,

velocities

Why is there a Need for Virtual Testing?

Manufacturing / Design Companies Need to: Reduce Product Development Time Reduce Overall Costs Improve Product Quality Daratech 1999

Virtual testing answers three questions: What does it look like?

- Ans: Design it in SolidWorks

Will it work?- Ans: Simulate it in COSMOS/Motion

Will it break- Ans: Analyze it in COSMOS/Works

simple 5-step process

The ease of use, speed, and power of COSMOS/Works & COSMOS/Motion does not require a dedicated analyst to produce useful results. You can make the overall process, which is often seen as very complicated to uninitiated users, simple by describing it as a simple 5-step process:

Define the geometry Define the component materials. Define the physical situation with boundary

conditions. Mesh the model and solve the analysis equations –

fast and simple. View and evaluate the computed results and

communicate them to others.
