摘　　要：使用ABAQUS有限元分析软件,考虑了轮胎的材料非线性、接触非线性以及大变形等复杂的力学特性,建立了光面和带有花纹块的185/70R14半钢子午线轮胎的两个三维有限元分析模型,通过改变气压、速度和摩擦系数等参数,得到了光面轮胎在静态接地、稳态滚动、加速刹车和侧偏工况下的接地印痕,研究了不同气压、载荷、速度和摩擦系数下接地印痕的变化;得到了带有花纹块轮胎的静态接地印痕,并考察了不同载荷下该印痕的变化。Using ABAQUS code, taken the material non-linearity,geometric non-linearity and contact non-linearity into account, two three-dimensional nonlinear finite element models including a smooth tread model and a pattern tread model for 185/70R14 half steel radial tire are constructed and used in this numerical study. Footprints of smooth tread model at static grounding, free rolling, motion,traction and corner rolling state are obtained with changed pressure, velocity, and coefficient of friction. Varieties of the footprints in different pressure, load, velocity and coefficient of friction are investigated. Footprints at static grounding of pattern-tire are obtained, and the variety with different loads is presented.
