摘 要: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 ,降噪效果越好 ;③花纹的节距比例应取无理数比 ;④花纹节距序列不要呈周期性排列 ;⑤花纹应有合理错位 ,但错位量与花纹周期不应成整数比 ;⑥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进行对比和择优 ,最后确定最佳设计方案。The principle and method of low noise tread patterns 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 tread patterns 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 said principle,the noises of these tread patterns 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.
