matlab编写的局部轨道不平顺，交点型轨道不平顺的（垂向，水平，方向，轨距不平顺）。-matlab prepared local irregularity, intersection type track irregularity (vertical, horizontal, direction, gauge irregularity).

以美国6级谱、车速100KM/h为例，进行轨道不平顺谱计算-United States 6 spectrum, speed 100KM/h, for example, be calculated track irregularity spectrum

生成铁道轨道不平顺，美国六级谱，一起讨论研究(Generating railway track irregularity)
