摘　　要：为改进某国产乘用车车体前端结构的抗撞性和验证目标分解方法的有效性,在其前端子结构特性目标确定的情况下,利用仿真试验和结构参数与结构特性之间的半经验关系进行了子结构及其结构断面参数设计方法的研究。整车正面碰撞有限元动态仿真结果表明,所设计的子结构使整车达到了总的目标要求。For impro,dng the crashwo;hiness of the front-end structure of a domestically produced passenger car and verifying the effectiveness of target cascading, the design methods of substructures and their structural cross- section parameters are studied by utilizing simulation test and the semi-empirical relationship between structural pa- rameters and structure characteristics with the characteristics objective of frontal Substructure definitely defined. The results of dynamic FE simulation on vehicle frontal crash show that the substructures designed meet the overall target requirements of vehicle.
