高速列车端墙的刚塑性动力分析

The Analysis of Rigid-Plastic Dynamics for the End Wall of High Speed Railway Vehicles

应用塑性动力学中的Ｈａｍｉｌｔｏｎ型变分原理对高速列车的端墙进行刚塑性动力分析，计算端墙受冲击后的变形过程及吸收的塑性功。为车体抗冲击设计提供理论依据。

This paper introduces the analysis of rigid-plastic dynamics for the end wall of high speed railway vehicles by using the “Estended Hamilton’s Variational principle”,and calaulates the plastic work and plastic deformation of the end wall when two railway trains impact to each other,which provides scientific basis for anti-impact design of the railway vehicles.
