包括simulink程序与轨道不平顺美国谱的时域生成程序（m语言编写的函数），直接可用于matlab的simulink模型仿真，不用做任何处理。下载该压缩包，打开其中的rail_excitation.mdl，双击即可看到时域轨道谱生成-Simulink program including the United States and track irregularity spectrum time domain generation program (m language function), can be used directly in matlab simulink model simulation, do not do anything. Download the archive, open one of the rail_excitation.mdl, double-click on the track to see the time-domain spectroscopy generated
