低噪声轮胎花纹设计原理与方法

阐述了低噪声轮胎花纹的设计原理与方法及低噪声评价准则，低噪声轮胎花纹设计原则如下，（1）不同花纹块和不同花纹槽的宽度比均应取无理数比，（2）花纹条数越多，降噪效果与花纹周期不应成整数比，花纹周期越长越有利于降噪，依据以上原则进行低噪声轮胎花纹设计，并进行微机仿真噪声模拟，再根据低噪声评价准则对花纹方案比和择优，最后确定最佳设计方案。

Principle and method of low noise tread patterns design

The principle and method of low noise treadpatterns} design and the assessment criteria of low noise are described. The principle of low noise tread patterns design is as follows :a) the width ratios between different tread blocks and different tread grooves should be irrational;b) the more tread ribs,the lower tread noise ;c) the pitch ratios of tread patterns should be irrational;d)the pitch series of tread patterns should not be arranged periodically ;e) the tread patterns units should be reasonably misaligned ,and the ratio between the deviation and the treadpatterns} period should not be integral;and the longer tread patterns'' period,the lower tread noise. The various tread patterns with low noise are designed based on the above saidprinciple,the noises of these treadpatterns are simulated by the computer,and the various designs are compared and optimized according to the assessment criteria of low noise to obtain the optimum design.
