路面不平度测量——进展与现状评述

Measurement of Terrain Roughness a State of the Art Review

本文综述了与地面车辆振动有关的路面不平度研究现状,指出了目前软路面不平度沿用硬路面不平度测量方法存在的问题,提出了软路面不平度的定义,并指出有必要研究各种条件下原始地面不平度、车辙不平度以及有效不平度三者之间的关系,为研究车辆振动和评价车辆振动性能提供科学的依据。

This paper reviews the state of the art on measuring roughness of pavement and terrain, points out the problems existing in current measurement of terrain roughness, gives the definition of roughness of terrain in vehicle dynamics, and indicates the necessity of researching relations of primitive roughness,rut roughness and effective roughness of terrain under different conditions for vehicle dynamics research.
