| 摘 要： | 地铁列车荷载模拟是进一步研究地铁振动的先决条件.针对轨道不平顺法在精度上的不足和车辆/轨道耦合模型在计算上的困难,建立列车荷载简化模型.在Simulink中仿真得到地铁列车荷载变化曲线,通过快速傅里叶变换分析列车荷载的频率成分,从而得到地铁列车荷载的模拟表达式.采用该分析方法所建的模型简单、计算速度快,同时也比不平顺法有更高的可靠性,可以满足一般性研究的需要.

| Abstract: | The simulation of metro train load is a prerequisite in further study of metro vibration.In order to overcome the imprecision of track irregularity method and the difficulties of the vehicle-track coupling model in calculation,a simplified model of the train load was built.The metro train load was simulated through the Simulink,frequency components of the train load were analyzed through the fast Fourier transform,then the simulation expression of the metro train load was obtained.The model built is quite s... |
