汽车车轮侧滑量检测存在问题及对策研究

Problems in Measurement of Automotive Wheel Side Slip and Corresponding Counter Measure

在分析侧滑产生机理的基础上,论述了目前侧滑检测中存在的检测结果离散性大、判定失准等问题。指出产生这些问题的原因除车速、载荷、胎压等因素外,还包括侧滑台的技术状况、检测站的设计形式等因素。针对问题提出了稳定检测条件、合理制定标准、提高检测技术等实现侧滑量准确检测与正确评定的有效措施。

On the basis of analyzing the generation mechanism of side slip,problems in measurement of side slip,such as great degree of separation,judgment out of truth,etc.,are discussed.It is pointed out that,besides velocity,load,tire pressure,etc.,technical state of side slip testing bench,design of measurement station are also reasons for these problems.In order to resolve these problems,effective measures for ensuring accuracy of measuring results and correct judgment,such as keeping stable measurement condition,developing reasonable standards and application of advanced measurement technology,etc.,are presented.
