| 中文摘要: |
| 针对11.00R20全钢载重子午线轮胎，利用Abaqus软件建立了轮胎-路面接触的三维有限元模型，通过耦合轮胎的垂直载荷、工况和侧倾角3个变量，模拟研究不同状况下轮胎-路面接触应力的变化情况。分析不同状况下轮胎的接地印痕应力云图，获得不同变量耦合作用下轮胎的接地应力变化趋势。本研究突破了以往常规静态或匀速条件下仿真结果的局限性，提高了计算的可靠度，可对轮胎-路面接触应力的研究及对路面保护、轮胎优化设计起指导作用。 |
| 英文摘要: |
| A three-dimensional finite element model of tire-pavement contact was established for
11. 00R20 truck and bus radial tire using Abaqus software, and the change of tire-pavement contact stress
under different states was simulated by coupling three variables which were tire vertical load，working
condition and cornering angle. Therefore, the changing trend of tire ground contact stress under the coupling
effect of different variables was obtained by analyzing the stress nephograms of tire ground footprints under
different states. This research broke through the limitations of the conventional simulation results under static
or uniform speed conditions，improved the reliability of calculation，and could guide the research works on
tire-pavement contact stress，pavement protection and tire optimization design. |
