Abstract:
      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.
