| 中文摘要: |
| 研究轮胎胎面磨损对车内噪声的影响。选用目前市场上常见的4家品牌轮胎，打磨至中度磨损程度（剩余花纹深度约为4 mm），并进行粗糙路面（60 km·h-1）和光滑路面（80 km·h-1）匀速行驶的车内噪声试验。结果表明，磨损后轮胎噪声水平总体变差，且轮胎的总声压级（20～2 500 Hz）、轰鸣噪声（20～200 Hz）、空腔噪声（200～250 Hz）和花纹噪声（500～2 500 Hz）与频率不呈线性关系。 |
| 英文摘要: |
| The effect of tire tread wear on the interior noise of vehicle was studied.Four common brands of tires in the market were selected，polished to a moderate degree of wear（the remaining pattern depth was about 4 mm），and the interior noise test was made at a constant speed of 60 km·h-1 on a rough road and 80 km·h-1 on a smooth road.The results showed that the overall noise level of the tire deteriorated after wear，and the relation of total sound pressure level（20～2 500 Hz），booming noise（20～200 Hz），cavity noise（200～250 Hz） and pattern noise（500～2 500 Hz） of various brand tires were not linear with frequency. |
