Abstract:

Article Preview

In this paper, the effect of material strain rate on the deforming process, the absorbing energy performance and the vehicle front longitudinal rails’ crash stress was researched.Furthermore, finite element model of a vehicle’s facial crash simulation was built up. Rigid wall facial crash simulation was carried out in two work conditions of considering front longitudinal rail strain rate and without considering it. Entire vehicle’s crash deceleraten was compared with test results. The results indicate that material strain rate has great effect on entire vehicle crash deceleraten, and the simulation result with considering material strain rate is more similar to test result than the one without considering it.
