摘要
在总结了目前应用的几种铁路轨道不平顺模拟方法的基础上，提出了一种新的模拟方法——频域法。这种方法不需要进行滤波，直接对轨道不平顺的功率谱密度函数进行采样处理，对平稳的及非平稳的轨道不平顺均可应用。数值模拟试验表明这种模拟方法简洁、实用、有效。
Based on summarizing the present simulating methods for the irregularities of railway track,a new simulating method,Frequency Domain Method (FDM),is put forward.The method does not need filtering and can sample directly from the power spectrum density function of the irregularity of railway track and be appliable for stationary and nonstationary railway irregularities.Numerical simuating tests demonstate that the FDM is concise,effective and powerful.
