| 中文摘要: |
| 对负荷变形后的轮胎花纹进行3D打印重构，分别对垂直对称花纹、点对称花纹和轴对称花纹3种花纹结构的轮胎模型进行风洞试验，获得轮胎花纹表面压力脉动（压力脉动）特性和花纹气动噪声（气动噪声）。结果表明，花纹结构对轮胎压力脉动特性有显著影响，压力脉动越大，其对应的气动噪声越高。研究结果为有效控制轮胎压力脉动、降低气动噪声提供了参考。 |
| 英文摘要: |
| The tire pattern after load deformation was reconstructed by 3D printing，and wind tunnel tests were performed on the tire models with vertical symmetrical pattern，point symmetrical pattern and axial symmetrical pattern respectively. The tire pattern surface pressure fluctuation（pressure fluctuation） characteristics and pattern aerodynamic noise（aerodynamic noise） were obtained. The results showed that the pattern structures had a significant effect on the tire pressure fluctuation characteristics. The greater the pressure fluctuation，the higher the corresponding aerodynamic noise. The results provided a reference for effectively controlling tire pressure fluctuation and aerodynamic noise. |
