| 中文摘要: |
| 研究轮胎空腔噪声的产生机理，并提出降低轮胎空腔噪声的应对策略。结果表明：轮胎空腔噪声频谱中出现的2个峰值是由轮胎变形引起的，导致了空腔模态的频率分叉；轮胎胎冠内表面粘贴吸声材料能够有效降低空腔噪声频谱峰值，部分车辆在轮胎空腔噪声频率相邻区间会出现恶化情况；调整胎体帘布层层数及和反包高度、三角胶高度、胎面胶类型及带束层角度对轮胎空腔噪声有明显的影响；轮胎阶次振动与空腔振动发生耦合时，通过工艺调整可以有效解决轮胎空腔噪声问题；轮胎内充气氦气可以消除不必要的噪声源。 |
| 英文摘要: |
| The generation mechanism of tire cavity noise was studied，and the response strategies were proposed to reduce tire cavity noise.The results indicated that the two peaks in tire cavity noise spectrum were caused by tire deformation，resulting in frequency bifurcation of cavity modes.Attaching sound-absorbing materials to the inner surface of the tire crown could effectively reduce the peak of cavity noise spectrum，and some vehicles would experience deterioration in the adjacent frequency range of cavity noise.Adjusting the number of ply layers and the height of the reverse wrap，the height of the apex，the type of tread compound and the angle of the belt had a significant impact on tire cavity noise.When the tire order virbration was coupled with cavity vibration，the process adjustment could effectively solve the problem of tire cavity noise.Inflating helium inside tires could eliminate unnecessary noise sources. |
