城市轨道列车车门结构瞬态响应研究

Urban Track Train Door Structural Transient State Impact Pressure Responding Studying

针对城市轨道列车的实际受力环境,运用有限元分析方法对轨道列车车门门体部分进行了瞬态响应研究。对结构的模态、阻尼特性进行了深入研究,并以此为基础对整体车门结构的动态响应进行了分析,分析表明结构的动态应力和位移满足强度要求和使用条件,为结构优化设计提供了重要依据。

In allusion to the real pressure of environment of the urban track train, it uses analytical method of finite element to respond and study the transient state to every parts of track train car. It carries on further investigation on the mode of the structure, damping characteristic. Based on this it analyzes the dynamic response of the whole door structure. The analysis indicates dynamic stress and displacement of the structure meet the intensity requirement and service condition, which offered the important basis for structural optimization design .
