摘　　要：为了在碰撞事故中有效的保护乘客的生命安全,汽车的车架必须符合一定的要求。特别是前部车架必须能够吸收一部分的能量,同时保证乘员能有足够的生存空间。针对一款燃料电池小车的车架,利用Hypermesh和Ls-Dyna软件,进行正面碰撞的计算机仿真模拟,分析得到的计算结果,提出相应的改进方案,并对改动前后的相关数据进行比较和验证。The design of car frame should follow some principles to protect the passengers effwiently in the car accidents. Especially,the front part of the car frame should be capable to absorb most of the crash energy,and enough surviving space must be guaranteed for the passengers. It focuses on a front crash simulation test of a fuel car frame ,and analysis the results by using the Hypermesh and Ls-Dyna sofiwares,Then,a primary improvement is suggested. Comparing the data with the previous one ,the ultima improvement is brought up and validated.
