帘线角度对轮胎静态接地工况影响的有限元分析

建立了9.00-20 16PR 载重斜交轮胎静态接地三维非线性有限元模型，分析了相同充气压力和下沉量下，帘线角度对轮胎接地状态下的变形、应力及应变的影响。结果表明，随轮胎胎体帘线角度的增大，轮胎断面宽、胎圈部位帘布层的层间剪切应力、胎体帘布第一主应力及第一主应变增大，而轮胎外直径、最大垂直接触应力及最大摩擦应力减小。;A three-dimensional non-linear finite element model of 9.00-20 16PR bias truck tire was established，with which the effect of the cord angle on the deformation，stress-strain behavior in the ground contact area of tire at the same inflation pressure and deflection was investigated.The results showed that the cross-sectional width of tire，the inter-laminar shear stress in cord plies of bead area，and the first principle stress and strain in cord plies increased，but the overall diameter of tire and the maximum vertical contact stress and friction stress decreased as the cord angle of carcass plies increased
