| Abstract: | The commercial vehicle front under protective device plays an important role in reducing the casualties of passengers in vehicle collision. This paper based on the Front Under Protective Devices regulation, established the finite element model of collision analysis with HYPERWORKS-LSDYNA software, has analyzed the front under protective devices collision performance in detail. The analysis shows that the collision performance of this front under protective devices confirms to the regulations、material fracture rate, the energy also verifies the reliability and authenticity of the simulation. |
