| 摘 要： | 通过有限元分析软件LS-DYNA 进行碰撞仿真分析,研究了某新开发的微型客车的100%正面碰撞性能.根据相应的国家正碰法规CMVDR294和GB 11551-2003对仿真结果进行评价,发现正碰仿真中车架变形量、车门框变形量以及前壁板入侵量过大,不满足设计要求.针对上述问题,结合车身具体结构特性提出了车架结构优化方案.采用仿真技术进行优化方案的筛选和验证.验证结果表明优化方案有效地提高了车身、车架结构的抗撞性能.为此类微型客车正面碰撞性能的分析与优化提供方法和理论基础.

| Abstract: | The front crash simulation based on LS-DYNA software is built to analyze the structural crashworthiness of mini-bus,which result evaluated according to the national frontal crash standard CMVDR294 and GB 11551-2003,indicates that the deformation of the frame,doorframe and front panel are too excessive in the simulation to meet the design requirements.In order to improve the crashworthiness of the bus,the optimization plans about the frame structure are proposed based on the structure characteristics of the ... |
