摘　　要：针对当前国内外路面不平度激励模型数目繁多、分类杂乱的现状,从平稳和非平稳两个方面归纳分析各类模型的特点、差异和适用范围。重点介绍几类新的理论方法在平稳和非平稳路面不平度模拟分析中的应用,指出当前研究存在的问题和不足,并对该领域下一步的研究方向做出展望。In view of existing various methods and complex classifications for road surface roughness excitation models, the characteristics, difference and application scope of each model were analyzed with both of stationary and non-stationary type. The applications of some new theories and methods in stationary and non-stationary simulation of road roughness are introduced, and the prospects for future research direction are discussed.
