摘　　要：采用Abaqus有限元分析软件,综合考虑12R22.5全钢载重子午线轮胎的实际结构并引入轮胎-轮辋、轮胎-地面的接触非线性边界条件,建立轮胎的有限元分析模型,对轮胎进行静负荷仿真分析,得到轮胎负荷与下沉量的关系及接地印痕和压力分布。与试验对比表明,模拟与试验结果吻合得很好。Based on the structure of all-steel radial truck tire,an axisymmetric model and a three-dimensional nonlinear finite element model for the tire with tread pattern are constructed by using the nonlinear boundary conditions,i.e.tire-rim contact and tire-road contact.The static loading of the tire is then simulated with the aid of ABAQUS finite element analysis software.The relationship between vertical load and shrinkage is acquired,and the contact patches and pressure distribution are obtained by pressure pad experiment and finite element modeling analysis.It is shown that the results predicted by simulation are in good agreement with experimental results.
