Abstract
This paper mainly studied the collision between heavy truck and rigid guardrail. The integral finite element models were established via respectively building the finite element model of truck and rigid guardrail and setting parameters of head-on collision. Then the paper did relative simulation and calculation, and analyzed the curves of vehicle speed, accelerated speed and energy in collision process. The whole process above used LS-DYNA to calculate, ANSYS to do pretreatment and LSPREPOST to do post-treatment in order to test collision safety. Compared with relative documents, the established model is basically correct and accords with the regular pattern of collision simulation.
