非承载式车身正面碰撞的数值分析

Numerical Analysis of Frontal Crash for Frame Car Body

非承载式车身结构的轻型客车发生正面碰撞时，车架是主要变形吸能结构。

In the frontal impact of a minibus , the most of crash energy is absorbed by the minibus 's frame structure .

对于非承载式车身结构的汽车，发生正面碰撞时，50%以上的碰撞能量由车架吸收，车架的耐撞性决定着整车的碰撞安全特性。

More than 50 % of the impact energy is absorbed by the frame for those vehicles with frame car body structure during frontal crash .

研究了车架、底盘、车身等对整个承载系统角刚度的贡献，证实了此类非承载式车身对加固车架的重要作用。

Research the contribution of frame , chassis , body etc to angle rigidity of the whole carrying system , verify the important effect on strengthening frame of non bearing body .

对于非承载式车身结构而言，车身与车架结构是其主要的承载部件，因此，车身与车架结构的一些性能指标必须满足相应的使用要求。

The body and frame structure is the main load-carrying components for the non-load-type body structure . The performance indicators of body and frame structure must meet the performance requirements of automotive products .
