| Abstract: | The finite element structural models of rubber and cast polyurethane road wheel are established by the software ANSYS. After calculating heat generation ratio of the nodes, the results can be used as the thermal loads on the finite element models of temperature field established. Based on the results of finite element analysis and test research, thermal characteristics of rubber and cast polyurethane can be contrasted, and some formulas are used to demonstrate thermal dynamic characteristics. |
