A Time-varying Coupling Model for Dynamic Analysis of High Speed Railway Subgrade

高速铁路路基结构时变系统耦合动力分析

The analysis program is compiled in this thesis and the dynamic response of high-speed railway vehicle-bridge coupling system is studied. Firstly, for the vehicle subsystem, a space vibration analysis model constituting of such rigid bodies as carriage, bogie frame and wheel is built.

编制了计算程序，并研究了高速铁路车桥耦合系统的动力响应。首先，针对车辆子系统，将车体、转向架、轮对简化为刚体，建立了车辆空间振动分析模型。

In order to analyzing the vehicle-track coupling vibration character of infinite length track, a time-varying model of railway tangent track spatial vibration was presented. This paper gives out states, feature and causes of alternately rail side attrition in the straight line intervals of railway.

针对无限长轨道上车辆轨道耦合振动响应特性，建立了铁路直线轨道结构空间振动模型。对铁路直线地段出现的钢轨交替不均匀侧磨的形态、特征以及成因进行了分析。
