自己摸索了很长时间，根据参考资料自己编写了一个用于生成轨道谱的程序，希望能够和大家一起分享^_^-Their own way for a long time, according to a reference to write your own program to generate spectral track, hoping to share with everyone ^ _ ^

自动生成美国6级轨道谱不平顺文件，可以用来作为铁道车辆的动力学仿真激励,Automatic generation of the United States six track irregularity spectrum of documents, can be used as a railway vehicle dynamics simulation incentive

利用matlab生成了德国、中国高低不平顺功率谱。(The high and low order power spectra of Germany and China were generated by matlab.)
