| 中文摘要: |
| 基于流固耦合仿真，应用计算气动声学方法对轮胎管腔共振噪声进行研究。滚动轮胎引起周围流体微粒间的相互作用被视为分散的四极子声源，基于Lighthill理论进一步求解并分析近场噪声和声学特性。通过对比接地前端、接地后端和胎侧位置声源的声辐射结果和频谱特性，验证了轮胎管腔共振噪声的产生机理。 |
| 英文摘要: |
| Based on fluid-structure coupling simulation，the resonance noise of tire pipe resonance noise was studied by computational aeroacoustic method.The interaction of fluid particles around a rolling tire was regarded as a dispersed quadrupole source.Based on Lighthill theory，the near-field noise and acoustic characteristics were further solved and analyzed.By comparing the sound radiation results and spectrum characteristics of the sound sources at the front end，rear end and tire side of the ground，the mechanism of the tire pipe resonance noise was verified. |
