摘要
本文运用有限元法，建立了列车通过时轨道结构振动分析模型。该模型考虑轨道结构竖向和纵向振动效应，计及轨道结构的不平顺影响。模型的动力响应输出量是轮轨竖向接触力、钢轨纵向力、剪力、弯矩、挠度和加速度。作为应用实例，文章对普通列车和重载列车通过时轨道结构进行了振动分析。
Using finite element method,a model of rail truck vibration analysis for moving trains isestablished in this paper,This model takes into account vertical end longitudinal vibrationeffects,as well as unsmooth behavier of rail line. The outputs for dynamic response are ver-tical wheel /rail interaction force,shear force,moment, deflection and acceleration in railtruck.As an application example,vibration analysis for moving normal trains and heavytrains are given.
