轨道不平顺的时域模拟法

Track irregularity simulation in time domain

在推导将轨道不平顺功率谱密度的空间频域表示转化为时间频域表示的基础上 ,提出了采用遗传算法来进行时域模拟的最佳滤波器的设计方法 。

On the basis of derivation of the power spectral density of track irregularity in time domain from in space domain, this paper puts forward the design method of optimized filter for its simulation in time domain by using Genetic Algorithms. The design results are given and its simulations are done.
