摘要
在原道路/轮胎噪声发声机理的基础上,对道路以及轮胎印痕前沿、中央和后沿的发生机理进行分析,对道路/轮胎噪声预测耦合模型表达式进行修正,并根据道路/轮胎噪声的产生机理提出了道路/轮胎噪声的降噪方法和路径,为低噪声路面和轮胎花纹的研究和设计提供了理论依据。
Based on the former sound generating mechanism of road/tire noise, the sound generating mechanisms of the road and tire noise from the front, central and back of ground contact area were analyzed,the prediction models of road/tire noise were modified, and methods to reduce the road/tire noise according to the generating mechanism of road/tire noise were proposed. This study provided theoretical bases for research and design of tire tread patterns and road with low noise.
