摘　　要：总结了当前时域路面建模中所用的几种方法,根据积分白噪声方法提出构造任意指定路面不平度系数路面的方法,利用虚拟激励法进行了证明,并对其离散化处理过程进行了推导,同时进行了仿真与验证。结果表明,利用此方法构造路面,过程简单,所构造路面的功率谱密度与给定功率谱密度符合较好。The current time-domain model used in building random road is summarized,proposed a way to construct any road which specified road roughness coefficient,according to the method of integrating white-noise,and proved it using pseudo-excitation method. Its discrete format,at the same time simulated and certificated this way is derivated.The results show that using this method to construct the road was simple,the power spectral density of road constructed with this method is in a good agreement with the given power spectral density.
