摘　　要：利用ABAQUS软件对三维轮胎接地模型进行建模,模拟了不同充气压力、不同垂直载荷下的轮胎接地情况,并对轮胎的静态刚度进行了分析。结果表明,固定垂直载荷下,随着气压的增大,法向应力最大值由胎冠两侧向胎冠靠拢。标准大气压下,随着载荷的增大,轮胎最大法向应力由胎冠中心向轮胎两侧移动。径向刚度、横向刚度、单位长轴纵向刚度、扭转刚度都与充气压力有关,只有扭转刚度受垂直载荷影响。ABAQUS software was used to model the three-dimensional tire-ground contact model,the grounding of the tire under different inflation pressures and different vertical loads was simulated,the static stiffness of the tire was analysed and discussed.The results showed that under fixed vertical load,the maximum of normal stress drew close to the crown from the two sides as air pressure increased.Under normal atmospheric pressure,the maximum normal stress of the tire moved to the two sides of the tire from the center of crown as load increased.Radial stiffness,unit longitudinal rigidity of long axis,torsional rigidity were all associated with inflation pressure,only torsional rigidity was affected by the vertical load.
