Based on FlowVision simulation software,the fluid-structure interaction method was used to numerically simulate the near-field noise of a tire.The flow field visualization results showed the motion of the flow field around the rolling tire.Comparing the near-field noise simulation with the experimental sound pressure level results,it was found that the experimental and simulation results had obvious directivity.The error of peak frequency between the simulation results and the test results in the 90° direction was only 4~8 Hz,and the test,simulation and theoretical calculation results had good consistency. 相似文献
