一种新型软路面不平测定装置

A New Type Measurer on Terrain Roughness

本文分析了当前软路面测定仪和软路面不平度研究状况,提出引起车辆振动的软路面不平度是等效软路面不平度、以及一种同时测取原始、等效和车辙地表不平度的新方法,并设计了一种同时测取三种软路面不平度的装置,为探索三种软路面不平度之间的关系奠定了测取基础.本文分析了测定装置的动态特性,并在SCHENCK振动台上进行了试验,结果表明:试验值与计算值吻合较好.

This paper analysed current terrain measurer and researched situation of terrain roughness.The effective terrain roughness have been proposed which results in vehicle vibration. A new method is put forward which may be used to measure the terrain roughness of original.effective and rut.We had designed an appropriate terrain measurer which may test three terrain roughness simultaneously.In order to explore some relationship among three terrain roughness,we attemp to establish measurment foundation.The paper analysed its dynamic charateristic.A vibration trial have been tested on SCHENCK exciting table.The conclusion obtained is close between experiment values and calculation values.
