CAE

  1. 1. CAE <ul><li>Computer-aided engineering (often referred to as CAE) is the use of information technology to support engineers in tasks such as </li></ul><ul><li>Analysis </li></ul><ul><li>Simulation </li></ul><ul><li>Design </li></ul><ul><li>Planning </li></ul><ul><li>Diagnosis, and repair. </li></ul><ul><li>Software tools that have been developed to support these activities are considered CAE tools. CAE tools are being used, for example , </li></ul><ul><li>Analyze the robustness and performance of components and assemblies. </li></ul><ul><li>Encompasses simulation, validation, and optimization of products and manufacturing tools. </li></ul><ul><li>In the future, CAE systems will be major providers of information to help support design teams in decision making </li></ul>
  2. 2. APPLICATION OF CAE <ul><li>Stress analysis on components and assemblies using FEA (Finite Element Analysis); </li></ul><ul><li>Thermal and fluid flow analysis Computational fluid dynamics (CFD); </li></ul><ul><li>Kinematics; </li></ul><ul><li>Mechanical event simulation (MES). </li></ul><ul><li>Analysis tools for process simulation for operations such as casting, molding, and die press forming. </li></ul><ul><li>In general, there are three phases in any computer-aided engineering task: </li></ul><ul><li>Pre-processing – defining the model and environmental factors to be applied to it. (typically a finite element model, but facet, voxel and thin sheet methods are also used) </li></ul><ul><li>Analysis solver (usually performed on high powered computers) </li></ul><ul><li>Post-processing of results (using visualization tools) </li></ul>
  3. 3. CAE IN THE AUTOMOTIVE INDUSTRY <ul><li>Reduce product development cost </li></ul><ul><li>Reduce time of testing </li></ul><ul><li>Improving the safety, comfort, and durability of the vehicles </li></ul><ul><li>Design verification </li></ul><ul><li>computer simulations rather than physical prototype testing. </li></ul>
  4. 4. SOFTWARE FOR CAE <ul><li>Software for Automotive crashworthiness and Occupant safety . </li></ul><ul><li>Altair RADIOSS, </li></ul><ul><li>LSTC’s LS-DYNA, </li></ul><ul><li>Cranes CAE suite [1] </li></ul><ul><li>ESI’s PAM-CRASH . </li></ul>
  5. 5. <ul><li>Software used in a variety of structural and dynamic analysis tasks </li></ul><ul><li>Eta/VPG, </li></ul><ul><li>NISA [2], </li></ul><ul><li>Altair HyperWorks[3], </li></ul><ul><li>BETA CAE Systems' [4], </li></ul><ul><li>MSC’s Patran, </li></ul><ul><li>MSC’s ADAMS, </li></ul><ul><li>LMS's Virtual.Lab [5], </li></ul><ul><li>SIMPACK [6], </li></ul><ul><li>NEi Nastran </li></ul><ul><li>UGS’s Scenario </li></ul><ul><li>Nastran packages </li></ul>
  6. 6. Software used to analyze functional performance of multi-disciplinary systems . LMS's AMESim .
  7. 7. LIMITATIONS OF CAE <ul><li>Physical testing is still used as a final confirmation for subsystems due to the fact that CAE cannot predict all variables in complex assemblies (i.e. metal stretch, thinning </li></ul>
