Key Benefits:听
- Virtually validate standard听tests听before听manufacturing a prototype听
- Cost and time reduction听
- Realize design changes at the early (virtual) stage听
New vehicle manufacturers must comply with several standards, one of them in North America is听,听ensuring听proper location听for occupant听restraint听and preventing听their failure.听听
This test requires pulling on seat belts with specific forces and at specific locations representing a person in the seat supporting an impact. This test is usually done with a physical prototype in certified test centers.
The best way to make sure these expensive tests will pass the test is to simulate them virtually using Finite Element Analysis during the design phase. ABAQUS explicit solver is used to realize this type of analysis.
The image shows听stress results in the seat and vehicle structures at some point in time during the pull test. In addition to stresses, bolts and rivets forces are evaluated to predict the pass or failure of the test. In this case, the customer was able to听modify the听design of the attachment听regions听to improve听local听rigidity听and听pass the test.听听
Leveraging听the听simulation technologies in such听an application allows for saving听significant time and money听since听failing听a physical test听is very costly both in time and money. Better to validate听tests听early in the virtual world where听design changes are听easy and quick to do.听
