| Abstract: |
| The finite element model of the 12.00R20 all steel truck and bus radial tire under rolling condition was established using Abaqus software. Under the rolling at the speed of 70 km·h-1，the change of speed and deformation of the model were processed by C programming language and the finite element grid was redrawn based on computational fluid dynamics(CFD).Then， the custom function was imported by using UDF in Fluent，and the fluid dynamics analysis was carried out.The Fluent analysis of the flow field was split into multiple time points and the interpolated values of the function were used in between.Then，the fluid dynamics simulation of gradually rolling tire and the flow field were obtained，and the effect of pattern blocks on the aerodynamic drag coefficient and flow field pressure was investigated.The results showed that， the aerodynamic drag coefficient of the tire with complex pattern blocks was bigger，where turbulence phenomena appeared，and the flow field pressure increased significantly. |
