| Abstract: |
| The ground contact characteristics of steel-belted radial tire under static and rolling conditions were experimentally investigated by using Tekscan pressure distribution measurement system.The results showed that，with the increase of inflation pressure，the contact pressure distribution of tire became even，the maximum contact pressure increased，and the stress concentration at shoulder was reduced.As the inflation pressure decreased，the contact width changed little，but the contact length and contact area increased.At the same pressure condition，the evaluation index of contact performance of rolling tire was generally smaller than that in the static state.Compared with the static condition，contact pressure distribution of rolling tire was more uniform，and the stress concentration at shoulder was smaller. |
