摘要
在ANSYS中建立了发动机盖的有限元模型,运用有限元法仿真分析了人-车碰撞时钢制梁式发动机盖的行人安全保护性,并将分析结果与试验结果进行了对比,证明了有限元模型的可靠性。针对铝制梁式发动机盖不能满足碰撞时行人安全保护的问题,对铝制发动机盖进行了结构设计。有限元仿真分析证明新设计的铝制发动机盖可以在满足轻量化要求的同时实现碰撞时行人安全保护目标。
The finite element model of engine hood is created in ANSYS. The pedestrian safety protection features of steel beam engine hood when people-vehicle collision is analyzed using finite element method. The results are compared with the experimental results, which show the reliability of the finite element model. Aiming at the issue of aluminum beam engine hood can＇t meet pedestrian safety protection in collision, the structure of the aluminum hood is redesigned. Finite element simulation analysis shows that the new designed aluminum engine hood can meet the lightweight requirement, while realize the target of pedestrian safety protection in collision.
