用于汽车轮胎力学特性研究的试验拖车

研究汽车在各种路面高速运动状态下的轮胎力学特性，为汽车的结构设计与改进提供试验数据。利用研制的试验拖车，通过在各种路面上的道路试验进行轮胎力学特性的各种研究，由此得到各种参数之间的相互关系及影响。试验结果表明，试验数据与理论分析基本吻合，证明拖车能够用于汽车轮胎力学特性的研究。

A Test Trailer Applied in the Study of Automotive Tyre Mechanical Characteristics

The tyre mechanical characteristics of an automobile moving at medium and high speed on different roads were studied to provide the automobile structure design and its improvement with test data. By using the test trailer developed, the relationship between various parameters and their mutual influences were obtained from the road test on different roads for automobile tyre mechanical characteristics. The road test result showed that the test data were in accord with the theory analysis, therefore the trailer can be used for measuring automobile tyre mechanical characteristics. Finally, an idea of improving the trailer was put forward according to the experiment result.
