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。 High-speed railway train load is a more complex issue, involving the train axle load, suspension system, speed, track composition, line smoothing and other factors. Based on the test of the test section, the influencing factors such as shaft weight, speed and track irregularity are considered. The sine excitation function is used to simulate the train load, which will provide reference and reference for the determination of dynamic load of high-speed train and the dynamic response of subgrade.
