我国采用美国铁路轨道不平顺功率谱密度函数进行轨道不平顺的数值模拟,所得结果与实测统计功率谱密度图相吻合,由此证明模拟的结果及方法是可靠的。
In our country, the numerical simulation of orbit irregularity is carried out by using the spectral density function of the irregular rail power in the United States. The obtained results are in good agreement with the measured statistical power spectral density, which proves that the simulation results and methods are reliable.
