摘　　要：考虑了轮胎的几何非线性、橡胶材料的非线性、橡胶物理体积的不可压缩性,建立了轮胎的三维有限元模型,分析了实心轮胎在滚动状态下的接触问题,考察了实心轮胎的变形、应力、应变、下沉量与载荷的关系。Dynamic response of a rolling solid rubber tire rolling over a rigid road is analyzed by an explicit finite element method. The frictional dynamic contact problem is formulated by making use of total Lagrangian scheme and the penalty method. The finite element model is established,and the stress, strain and deformation, the relationship between load and deformation are discussed.
