摘要
在地铁车辆碰撞分析中有限元求解软件得到普遍采纳。本文以某不锈钢地铁车辆为研究对象,借助通用显示有限元求解软件PAM-CRASH进行数值仿真,得到两列相同编组地铁车辆碰撞过程的变形趋势、能量曲线和撞击力曲线,进而评价车体的被动安全性能,并验证壳单元积分算法、沿单元厚度的积分点数和沙漏控制方法设置的合理性。合理的参数设置提高了数值分析结果的准确性,为地铁车辆的碰撞分析提供一定的理论依据。
Explicit finite element solver software was universally adopted in the subway vehicle crashworthiness analysis. Take the stainless steel as subject,get the deformation trends,energy curve and force curve of collision course of two identical grouping subway vehicle by explicit finite element solver software PAM-CRASH,and evaluate passive safety performance of the vehicle,verify the reasonableness of shell element integration algorithm,the number of integration points along the thickness of the element and hourglass control method. The accuracy of numerical analysis was improved by abundant parameters,the accuracy of numerical analysis was improved by abundant parameters,and the theoretical basis of subway vehicle collision analysis was provided by the calculation results.
