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

•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.
