利用结构非线性有限元计算程序LS-DYNA,对具有相同截面积,但不同形式的铝合金薄壁元件进行轴向低速冲击仿真计算,分析各种元件的吸能特性,获得一种适用于轨道车辆前端大吸能量要求的吸能元件。
Using the structural nonlinear finite element program LS-DYNA, the axial low-velocity impact simulation of thin-walled aluminum alloy thin-walled elements with the same cross-sectional area and different forms was carried out to analyze the energy absorption characteristics of various elements and obtain a suitable low- Energy absorption elements required for large suction energy at the front of the vehicle.
