Front crash has high probability in tranfic accident, and the front energy absorption part plays a very important role during the crash and is the key point to protect the safety of the occupant. The whole vehicle front crash is simulated in software LS-DYNA. This paper fix out the key steps and parameters in FEMB, and make good advise for finite anlysis. Finite anlysis is used in this paper to study motionstate of the vehicle and the energy absorption. Due to the anlysis, we find out that the front longitudinal beam is the most important component in the crash.
