| Abstract: |
| The finite element analysis（FEA）on 12.00R20 all steel radial truck tire under the pure rolling condition was carried out by using Abaqus software，the node position，element and speed of the outer surface of tread groove were obtained，and a secondary development on Fluent software was carried out.Combined with the FEA data，the three-dimensional flow field of the air pumping noise of tread groove of the tire under the pure rolling process was simulated by using Fluent software to calculate the pressure field of three kinds of typical groove pattern.The noise of far field point was solved by integration method.Then，the noise characteristics of those three kinds of typical groove pattern were comparatively studied.The calculation results were in good agreement with the conclusion from tests and theoretical analysis. |
