| 中文摘要: |
| 研究横向细沟槽对轮胎胎面花纹噪声的影响。结果表明，无论加刻什么类型的横向细沟槽，声压级都大幅升高；速度对声压级的影响程度大于负荷；在3种类型的横向细沟槽中，S形直沟槽噪声较小，且正、反转时声压级差异小；15°斜沟槽声压级较0°与15°交替排列沟槽略高，但0°与15°交替排列沟槽的正转和反转声压级差异较大。 |
| 英文摘要: |
| The effects of narrow transverse grooves tread pattern on tire noise were investigated.The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger. |
