路面不平度研究综述

A survey of road roughness study

回顾了近年来汽车理论研究和道路谱分析领域中路面不平度的理论研究和发展现状。根据研究方向不同,分别从理论研究、试验分析和工程应用三个方面进行讨论。理论研究主要从路面不平度的定义出发,分析了其数学模型的研究进展;试验分析包括路面不平度测试测量技术的发展和不同类型试验分析与仿真计算的研究状况;路面不平度的工程应用主要针对其在汽车和道路各个方面的应用进行了讨论。综合论述了路面不平度的原理、特点及其在工程中的应用,最后还特别针对利用中国典型道路的路面不平度数据进行汽车设计与开发进行了阐述,并对路面不平度的研究前景进行了探讨和展望。

It was reviewed that the progresses of road roughness study in field of automobile engineering and transportation engineering in recent years. Based on different investigation contents,three aspects were discussed. First of all,the basic theory including the definition of road roughness and the mathematical model of road roughness in the form of power spectrum was reviewed;secondly,the experiment analysis including the development of instruments of measurement and the progresses of test and simulation in road roughness was reviewed;thirdly,the application of road roughness in engineering of automobile engineering and transportation engineering was discussed. The principle,characteristics and application in engineering of many kinds of road roughness in field of automobile engineering and transportation engineering were discussed synthetically. In addition,the roughness data of the Chinese representative road were mentioned,which were used to study and design automobiles in China. In the end,the prospects of road roughness study were summarized.
