| 中文摘要: |
| 选取不同规格的C1及C2轮胎，利用轮胎噪声试验台架进行轮胎单体花纹噪声声功率测试，研究轮胎规格对轮胎单体花纹噪声声功率的影响。结果表明：轮胎断面宽对声功率影响较大，断面宽越大，声功率级越高；断面高宽比对声功率影响较小；速度对声功率频谱的影响主要集中在100 Hz以上频段，在40～100 Hz频段内影响很小；声功率频谱在
1 000和2 000 Hz处存在明显峰值。 |
| 英文摘要: |
| Selecting C1 and C2 tires of different specifications，the sound power of single tire pattern noise was tested by tire noise test bench to research the effect of the specifications on pattern noise power of single tire.The results showed that the tire section width had great effect on the sound power，and the larger the section width was，the higher the sound power level was.The ratio of height to width of tire had little effect on the sound power.The effect of speed on sound power was mainly concentrated above 100 Hz frequency band，and the effect of 40～100 Hz frequency band was small.The sound power spectrum had obvious peaks at 1 000 and 2 000 Hz. |
