| Abstract: |
| In this study，using 385/55R2.5 truck and bus radial tire as an example，the influence of inner contour，bionic tread arc and belt structure of tire on the grounding characteristics and crown temperature distribution was investigated by finite element analysis.The results showed that，inner contour and bionic tread arc significantly affected tire crown temperature，and the crown temperature of the tire with 4-layer belt structure was lower than that with “3＋0°” belt structure.It was found that the average ground contact pressure，ground contact area，hardness coefficient，ground contact width，ground pressure deviation and footprint area of tire were strongly associated with tire crown temperature. |
