| 中文摘要: |
| 通过对不同花纹沟轮胎发声机理的研究，建立预测数学模型，模拟计算具体的发声情况，提高轮胎花纹的设计水平。研究结果表明，对于与轮胎中心线成一定角度的花纹沟，其深度和宽度对轮胎噪声的影响不大，而花纹沟角度的影响很大，其每增大15°，轮胎的噪声声压将提高110％～130％。 |
| 英文摘要: |
| Based on the sound emission mechanism in different tread grooves，a mathematic model was established to simulate the sound generation and modify the tread patterns design.The results showed that the depth and width of the groove with a certain angle to the central line of tread had little effect on the tire noise，but the angle of groove had great effect on the tire noise，and the sound pressure of tire noise would increase by 110%～130% with every 15° increase of angle of groove. |
