CAE SIMULATION ANALYSIS AND RIG TEST VALIDATION RESEARCH OF AUTOMOBILE LEAFSPRING (MT)

There are two methods to verify the durability characteristics of a new designed leafspring, there are physical test which takes more time and cost and CAE simulation which is time-saving and cost-saving. Aiming at coming up an effective CAE simulation of the leafspring life, the CAE simulation for stiffness and strength with rig test is validated. Base on the validated CAE method, with material property from test, CAE fatigue simulation is conducted with different surface treatment factor and validated with rig test to find out the best parameter for good life correlation. Finally, an effective CAE life prediction of automotive leafspring is provided, and the solution can serve as a good reference for the industry.
