| 中文摘要: |
| 研究轮胎噪声的测试和评价方法，分析轮胎噪声的影响因素。结果表明，横向沟槽形状对轮胎噪声影响很大，90°横向沟槽的轮胎噪声最大；随着轮胎沟槽深度的增大和沟槽数目的增加，轮胎噪声增大；横向封闭沟槽轮胎噪声高于同样形状大小开放沟槽轮胎噪声；对于有方向性要求的花纹，沟槽方向对轮胎噪声的声压级和频谱曲线有较大影响；改变轮胎的高阶振动模态特性，可以降低轮胎的噪声。Zwicker响度与主观评价有较高的一致性，可以作为轮胎噪声客观评价指标。 |
| 英文摘要: |
| The methods for measuring and evaluating tire noise were investigated and the affecting factors on tire noise were analyzed.The results showed that the shape of transverse groove had significant effect on the tire noise and the 90° transverse groove generated the highest noise；the tire noise increased as the groove depth and number increased；the noise of tire with closed transverse groove was higher than that with similar open groove；for the directional tread patterns，the direction of groove had greater effect on the noise level and frequency curve；and the tire noise could be decreased by changing tire modality at high frequent vibration.The Zwicker loudness was well in accordance with the subjective judgment，so it could be used as an index of tire noise in objective evaluation. |
