| 摘 要： | 高速铁路列车荷载是一个比较复杂的问题,同时涉及列车轴重、悬挂体系、行车速度、轨道组成、线路平顺等因素。在试验区段测试的基础上,考虑了轴重、速度、轨道不平顺等影响因素,采用正弦激励函数模拟列车荷载,以期为高速列车动荷载的确定和路基动力响应分析提供借鉴和参考。

| Abstract: | Load of high-speed railway is a complex issue,which involves many factors such as axle weigh,suspension system,running speed,track structure,railway track smooth and so on.Based on the checkout of test section,taking axle weight,speed and track irregularity into consideration,the sinusoidal excitation function is adopted to simulate the train load.The present essay aims to offer references for the determination of dynamic loads of high speed trains and dynamic responses of sub-grades. |
