摘　　要：本文针对需要转接法测试轮胎湿路面相对抓着性能指数时,如果试验轮胎和参照轮胎的用途不同,比对研究了参照轮胎的湿路面相对抓着性能指数计算方法,试验结果表明,参照轮胎的湿路面相对抓着性能指数的计算按照试验轮胎的用途所对应的计算公式进彳亍计算时试验轮胎的湿路面相对抓着性能指数的计算值与实际值更接近.In this paper,when the transfer method is needed to test the tire wet grip perfonnanee index,if the category of use of the test tire and the reference tire is different,the calculation method of the control tire wet grip perfonnance index is compared and studied.The test results show that,referring to the calculation of the wet grip performance index of the control tire,when calculated according to the category of use of the test tire,the calculated value of the wet grip performance index of the test tire is closer to the actual value.

关 键 词：转接法 抓着性能指数 参照胎 轮胎用途
