微型客车耐撞性的改进方法及应用

An Innovative Approach to Minibuses′ Crash Performance and its Application

针对某微型客车进行了耐撞性分析 ,找出其不满足我国正面碰撞乘员被动安全性法规要求的原因 ,并对提高其车身结构被动安全性的方法进行了研究。通过建立相应的力学目标和利用计算机模拟分析手段 ,提出既对原车身结构改动小 ,又能有效提高被动安全性的结构改进措施。对该车改进后的结构进行了正面碰撞计算机模拟和实车实验 。

In this paper,the reason that the minibus did not meet with the standard and the methods used to improve passive safety in frontal impact of minibus were studied.Based on mechanics modeling and computer simulation,the minibus structure modifying technique and designing method are put forward.The result of computer si mulation of frontal impact is consistent with that of experiment for the improved structure.
