| 中文摘要: |
| 以8种规格的轿车轮胎为对象，研究行驶速度、负荷、充气压力以及测试角度和距离对轮胎室内噪声的影响。结果表明：轮胎噪声声压级随着行驶速度的提高而增大；负荷和充气压力对轮胎噪声的影响不大，但在负荷率为50%时噪声声压级出现拐点；在不同测试角度和距离所得到的轮胎噪声声压级有明显的指向性和衰减规律 |
| 英文摘要: |
| Taking 8 types of passenger car tire as the object，the effects of velocity，load，inflation pressure，test angle and distance on the indoor noise of tire were investigated.The results showed that the sound pressure level of tire noise increased with the increase of velocity；the load and inflation pressure had little effect on tire noise，but the sound pressure level had an inflection point when the load rate was 50%.The obtained sound pressure level of tire noise had obvious directivity and attenuation regular. |
