摘要
利用显式有限元方法对不同厚度、不同截面形状以及不同预变形的薄壁结构碰撞性进行了仿真计算,通过分析比较,得到结构参数对碰撞性能的影响以及薄壁结构的基本碰撞规律,为车辆耐碰撞性能的设计奠定了基础。
The explicit finite element method was adopted to simulate and calculate the crash performance of thin-wall structures of various thicknesses, cross-section shapes and foreordained deformations. The analysis and comparison of simulation results bring about the understanding of the influence of structural parameters on crash performance and of basic laus of crash by thin-wall structures, which lays foundations for the design of autorriotives' crashworthiness.
