摘要
建立了某型客车车身骨架几何实体模型与碰撞有限元模型;基于著名的显式动力分析程序LS-DYNA,对其正面碰撞过程进行了求解分析;并在现有商业建模软件的基础上,讨论了碰撞仿真建模中的一些应用技术要点。
The geometric solid model and the finite element model of the body skeleton of a passenger coach are established.Based on the famous explicit dynamical analysis program LS-DYNA,this paper gives the solution and analysis on frontal crash,and discusses the key technical points of crash simulation and modeling on the basis of existing commercial modeling software.
