摘　　要：为了得到轮胎力传递率结果,首先设计了试验,根据传递函数相关理论进行了严密的公式推导,得到了轮胎横向和垂向的力传递率计算公式,然后通过该试验方法和计算公式对正开发项目的 3种备选轮胎进行了试验,最后对试验结果进行对比分析。结果显示:设计的试验方法简单、有效,通过推导公式计算得到的轮胎力传递率结果准确,能为轮胎选择提供依据。In order to get the wheel and tire force transmissibility, the test is designed and the formula is deduced by transfer function theory to obtain lateral and vertical force transmissibility, and then three wheels are tested by the test method; finally, the results are calculated and comparative an- alyzed. The results show： the test method is simple and effective, the force transmissibility results by derivation formula are accurate, and can provide the basis for the tire choice.
