| 摘 要： | 针对钢制发动机罩盖不能满足行人碰撞保护法规要求的问题,对钢制发动机罩盖进行了材料替换和结构设计.在ANSYS中建立了头块和发动机罩盖的有限元模型,通过有限元仿真分析结果与试验结果的对比,证明了有限元建模的可靠性.对新设计的波纹式铝制发动机罩盖和原来的梁式钢制发动机罩盖进行了有限元仿真分析与对比.研究结果表明,新设计的波纹式铝制发动机罩盖可以有效地减小人-车碰撞过程中行人头部伤害值,满足行人碰撞头部保护标准.

| Abstract: | Aiming at the steel engine hood coudn’t meet the requiements of pedestrian impact protection regulation,the steel materials were insteaded by aluminum and the structures were redesigned to the engine hood.The finite element model of head block and engine hood were built in ANSYS.Through the comparison between finite element simulation and test results,the reliability of the finite element model was proved.The finite element simulation analysis was done to the newly designed wave type aluminum engine hood and the original beam type steel engine hood.The comparison results show that the newly designed structure can effectively reduce pedestrian head injury criterion,meet the pedestrian impact head protection standard. |
