| 中文摘要: |
| 针对轮胎花纹噪声仿真分析结果与实测数据存在差异的问题，进行了室内不同方位轮胎花纹噪声测量试验。试验发现，轮胎花纹噪声的发声类似扬声器发声，有极强的指向性，若仅用一个测点的噪声声压级评判噪声的大小会导致方案排队和择优上的困难与矛盾。经分析研究，提出了一种全方位测定轮胎花纹噪声的方法，并制定了测量规范。 |
| 英文摘要: |
| The difference between the simulated tread patterns’noise and the measured value was investigated by measuring the tread patterns’noise at the different indoor places.The test results showed that the wrong plan for lowering the tread patterns’noise would be obtained if the noise level was judged by the sound pressure level of noise measured only at one place because the emission of tread patterns’noise was similar to that of loundspeader sound and had strong orientation.So，a new method for measuring the tread patterns’noise in multi-directions was proposed. |
