| 摘 要： | 提出了一种客车侧翻一步碰撞快速算法,利用该算法对某款长12 m的公路客车典型车身段进行了侧翻碰撞模拟,并与LS-DYNA仿真及侧翻试验结果进行了对比,结果表明,侧翻一步碰撞快速算法可以较好的预测客车结构的侧翻安全性能,其模拟结果与其它两种方法之间的误差小于15%,模拟时长约为LS-DYNA仿真的1/10,在基本保证计算精度的同时使得计算效率大幅提升。

| Abstract: | A one-step fast algorithm of bus rollover collision is proposed in the paper used to conduct rollover collision simulation for typical body of a 12 m length bus, the simulation is compared with LS-DYNA simulation and rollover test results. The results show that this one-step fast algorithm can predict safety performance of bus structure in rollover, and the error between the simulation with two other methods is less than 15%, the simulation duration is approx. 1/ 10 of LS-DYNA simulation, which increases calculation efficiency greatly while ensuring calculation accuracy. |
