带复杂花纹轮胎侧倾接地性能有限元分析

使用组合二次周向保角映射建模法建立12.00R20全钢载重子午线轮胎带复杂花纹的三维有限元模型。采用有限元分析软件ABAQUS模拟标准充气压力和负荷下轮胎的侧倾滚动状态，研究轮胎的侧倾角对接地面积和接地压力分布的影响。另外，通过定义自接触面分析侧倾滚动工况下花纹沟的闭合情况，结果表明该方法是可行和有效的。;A three-dimensional finite element model of all steel radial truck tire 12.00R20 with complex tread pattern was established by using circumferential conformal mapping method.The tire rolling states with different camber angles were simulated under standard pressure and load by using ABAQUS finite element analysis software.The influence of camber angle on the contact area and contact pressure was investigated.In addition，the influence of different rolling states on the closed area of pattern groove was also studied by defining self contact surface，and the results showed that this method was feasible and effective
