潮湿路表条件下轮胎噪声的模拟方法

The Simulation Method of Tire Noise Under Wet Road Condition

路面行车噪声对道路沿线居民和车内人员带来较大危害,且路面有水状况下行车噪声比干燥状态下响度更大、高频噪声的频率更高。研究表明,潮湿路面上噪声与轮胎-路面间的接触状态具有一定关联性,因此,本项目论证的模拟方法较为准确地得到与实际相近的数值,为潮湿路面行车噪声数值预测奠定基础。

The traffic noise on the road has brought great harm to the residents and occupants along the road, and the traffic noise on the road with water is louder and the frequency of high-frequency noise is higher than that on the dry road. The research shows that the noise on the wet road surface has a certain correlation with the contact state between tires and road surface. Therefore, the simulation method of tire noise under the wet road surface demonstrated in this project can accurately obtain the value close to the actual value, which can lay a foundation for the numerical prediction of traffic noise on the wet road surface.
