Multi-Body Dynamics Simulation and Finite Element Analysis of the Car’s Sub-Frame

Abstract:

For the problem that car sub-frame constraint connection complex and effective load more difficult to determine, using finite element and multi-body dynamics ADAMS co-simulation method, Analyzed on a Volkswagen vehicle sub-frame, obtained the accurate load on the sub-frame which are used by engine suspension. The finite element analysis results show that engine load is the greatest impact on the sub-frame stress field, which can be reduced by increasing the area of engine and the sub-frame contacting, thereby prolong the life of sub-frame.
