| Abstract: |
| The computer simulation and optimum design technology of radial tire performance were introduced taking 205/60R15 passenger car tire as example.The tire profile curves were digitalized and the FEM module including the layer unit was used in the CAD model of tire structure design to cont rol the total number of finite elements in tire model.By means of the established tire model on this basis，the various working coditions of 205/60R15 passenger car t ire，such as free condit ion，static inflated condition，rotat ing inflated condition，ground-contact condi tion，as well the working condition on the driven wheel under the coaction of horizontal traction and vertical load were simulated，and the influence tendency of belt cord angle and pseudo carcass cord extension value on the tire perfo rmance was given.It was found through the test that the analysis results of simulation were in accordance with the test results. |
