Laboratory Prediction of Tire Tread Wear and associated high frequency Vibrations

摘要

The mechanism of tire wear and rubber wear test methods have been researched for more than a century ever since the advent of pneumatic tires. In 1929, Lam-bourn l was the first to propose and patent a laboratory wear tester that correlated with tire wear test results. From excerpt of Lambourn's results, Mouri 2 found a decent correlation between rubber wear test and tire test, where the correlation coefficient was as high as R2 = 0.96, although the range was quite wide with nearly four-fold difference between the worst compound and the best compound. This may not be practical when a 20 to 30 difference in wear rate is of interest in most studies. According to Lambourn, slip ratio of tires was about 1 for normal driving and about
