分析了轨道不平顺产生的原因,介绍了轨道不平顺的测量方法以及应用随机振动理论对轨道不平顺进行特征统计的参数,并采用三角函数法求得轨道系统随机不平顺的模拟量,从而为研究列车-轨道系统的动力学效应提供了一种简便方法。
The reason of track irregularity is analyzed. The measuring method of track irregularity and the parameter of track irregularity using stochastic vibration theory are introduced. The random quantity of track system is calculated by trigonometric method, The study of the kinetic effects of train-rail systems provides a convenient method.
