列车-可动心轨式道岔空间耦合系统动力分析

Dynamic Analysis of Space Coupling System of Train Turnout with Movable Nose Frog

基于可动心轨式道岔结构的主要特点，建立了列车－可动心轨道岔系统空间耦合振动分析模型，并用于分析不同车型的列车、速度、轴重等因素对我国１２号可动心轨提速道岔动力特性的影响。

On the basis of structure characteristic of turnout with movable nose frog, a space coupling system model is presented for train turnout with movable nose frog,and it is used to investigate the influence of train type,train speed and axle load on the dynamic characteristic of Chinese No.12 raising speed turnout with movable nose frog.
