大客车车身骨架侧面碰撞模拟分析

阐述了汽车碰撞有限元法和接触碰撞系统,模拟了大客车与大客车侧面碰撞,并从骨架结构变形、乘员生存空间、碰撞能量、碰撞速度和加速度方面详细分析了撞击和被撞大客车车身骨架碰撞安全性,提出了提高大客车车身骨架耐撞性的方法。

The finite element method of bus crash and the contact collision system are expatiated. Bus to bus side crash is simulated. The bus side crash safety performance is analyzed from the aspects of structural deformation, passenger living space, collision energy, velocity and acceleration of the bus frame. The method to improve the safety of bus frame side crash is put forward
