Abstract:
      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.
