Finite element modeling of vehicle side crash

Crash simulation of full car is a pivotal and effective method to study vehicle passive safety. According to European side crash regulation, ECER95, the side crash property of a native car is ana-lyzed by USA ETA/VPG and LS-DYNA softwares. The modeling and simulation of full car and full-scale side crash are introduced in detail. The crucial aspects related to the accuracy of the result, such as the simulation of materials and spot welds, the time control, rigid body, and the definition of contact interface are discussed. The comparing results between simulation and full-scale test indicated that the deformation, acceleration and motion of vehicle body are consistent. The modeling method of vehicle side crash is validated.
