| 中文摘要: |
| 借助最新研究开发的“轿车轮胎微机仿真系统”及“轮胎花纹噪声级频谱评判法则”成果，研究低噪声轮胎花纹设计方法与原则，经理论分析和实验验证得出，胎面花纹排列节距比、轮胎圆周上同类花纹重复排列的周期之比、各花纹块面积之比、槽沟之间的距离之比以及各沟槽面积之比均宜取不接近于整数的无理数，横向沟槽、细长沟槽及横向或纵向死沟的噪声较大。 |
| 英文摘要: |
| The design priciple and method of tread pattern with low noise are investigated with the aid of the newly developed computer simulating system of passenger tire and the assessment rule for the noise spectrum of tread pattern. The theoretic a nalysis and the experimental verification show that the arrangement pitch ratio of tread patterns，the repeat period ratio of the same element forming ribbed patterns on the tire circumference，the area ratios of both tread blocks and grooves，and the ratio of the distances between grooves should be an irrational number far from a round number；the lateral groove，the long narrow groove，and the lateral or longitudinal groove with only one open end produce higher noise. |
