| 中文摘要: |
| 以12R225轮胎为研究对象，建立全花纹全钢子午线轮胎与地面接触的三维非线性有限元仿真模型，研究不同负荷、充气压力和工况下轮胎的接地压力变化规律。结果表明：花纹接地压力分布仿真与实测结果吻合；随负荷增大，接地压力增大且向肩部偏移；充气压力增大；轮胎中心区域接地压力增大；启动、侧偏和转弯等复杂工况对接地压力分布影响显著。 |
| 英文摘要: |
| Taking 12R225 tire as the research object，the three-dimensional nonlinear finite element simulation model of all tread pattern all-steel radial tire contacted with the ground was established，and the variation law of tire contact pressure under different load，inflating pressure and working conditions was studied.The results showed that，the simulated pattern contact pressure distribution was consistent with the test results.With the increase of load，the contact pressure increased and shifted to the shoulder.With the increase of inflating pressure，the contact pressure at the tire center area increased.The complex working conditions such as start-up，sideslip and turning had a significant impact on the contact pressure distribution. |
