摘要：

为避免某车型侧面刚性柱碰撞中存在的车身结构变形过大，胸部压缩量超标的问题，优化
和改进了该车身结构。根据座椅安装横梁、地板严重扭曲，乘员生存空间不足的试验结果，建立车
身结构及约束系统侧面柱碰撞模型；根据侧面结构耐撞性的设计原则，变更了车身结构和材料等级。
结果表明：优化后车身侧面结构强度得到有效提升，侧柱碰前车门的最大侵入量降低13%，增加了侧
面约束系统的缓冲空间，降低了假人胸部的伤害值。因而，这些改进，满足了整车侧面碰撞安全目标。

Abstract:

A car body structure was optimized and improved to avoid excess driver chest compression
caused by excess intrusion in side rigid pole barrier crash. A reliable and credible body structure was set up
with a restraint system model in side pole impact based on the test results which had seriously distorted seat
installed beam and floor with insufficient occupant living space. The body structure and the material grades
were modified by the design principles for lateral structure crashworthiness. The results show that the final side
body strength is effectively promoted, the maximum intrusion of front door in side pole impact decreases by 13%
with increasing the lateral restraint system buffer space, and reducing dummy chest damage. Therefore, these
improvements meet the safety goals of body structure in side impact.
