| 中文摘要: |
| 以12R22.5全钢载重子午线轮胎为例，采用某有限元仿真分析软件建立三维有限元模型，分析轮胎在静态加载、制动和驱动状态下与路面间的相互作用力。结果表明：自由滚动状态下，轮胎的接地印痕面积小于静态加载状态下的接地印痕面积，且自由滚动状态下的压力区域更为集中，最大压力值大于静态加载状态下的最大压力值，随着自由滚动速度的增大，轮胎的接地印痕面积逐渐减小，接地压力逐渐增大；制动状态下，轮胎的接地印痕前端的接触面积小于后端的接触面积，印痕前端压力大于后端压力；驱动状态下，轮胎的接地印痕前端凸出，后端趋近为水平线，印痕前端压力小于后端压力。 |

| Taking 12R22.5 all-steel radial truck and bus tire as an example，a three-dimensional finite element model was established using a certain finite element simulation analysis software to analyze the interaction forces between the tire and the road surface under static loading，braking，and driving states.The results showed that in the free rolling state，the contact mark area of the tire was smaller than that in the static loading state，and the pressure area in the free rolling state was more concentrated，with the maximum pressure value greater than that in the static loading state.As the free rolling speed increases，the contact mark area of the tire gradually decreased，and the contact pressure gradually increased.In the braking state，the contact area at the front end of the tire""s ground contact mark was smaller than that at the rear end，and the pressure at the front end of the mark was greater than that at the rear end.In the driving state，the front end of the tire""s ground contact mark protruded，and the rear end approached a horizontal line.The pressure at the front end of the mark was lower than that at the rear end. |
