摘　　要：根据轮胎材料非线性、接触非线性以及大变形等复杂的力学特性,利用加强筋单元描述钢丝帘线-橡胶复合材料,建立了10.00R20全钢载重子午线轮胎的三维非线性有限元模型。借助有限元分析软件MSC.MARC,分析了轮胎在充气压力、垂直载荷以及稳态滚动下各带束层中的应力分布情况。结果表明:在这3种工作状况下,各带束层中的应力分布和大小发生了较大变化;给出了带束层应力在此3种情况下的变化规律。According to the tire material non-linearity, geometric non-linearity and contact non-linearity a three-dimensional nonlinear finite element model of 10.00 R 20 all steel radial truck tire was constructed by means of MSC. MARC software, in which steel cord-rubber composites were modeled by rebar element. The distributions of stress in different position of each belt were given out, when inflation pressure, vertical load and steady rolling were applied to the tire. The results showed that under these three load cases, great changes of stress distributions and magnitude had taken place in belts. The laws of stress distribution in each belt were given in this paper.
