| 中文摘要: |
| 基于有限元的轮胎疲劳寿命评价方法，建立295/80R22.5全钢子午线轮胎的有限元模型。使用ABAQUS隐式分析方法获得轮胎的应变、应力以及应变能密度等基本参数后，根据轮胎实际使用中的破坏情况选择影响疲劳寿命的评价指标。结果表明：高速耐久工况下，应选择应变能密度和帘线张力作为影响疲劳寿命的评价指标，而且适当增加带束胶厚度能有效提高轮胎的疲劳寿命；低速重载工况下，应当选择帘线和橡胶间的剪应力（层间剪应力）作为影响疲劳寿命的评价指标，且适当降低胎体帘布层和补强层的高度能有效提高轮胎的疲劳寿命。 |
| 英文摘要: |
| On the basis of tire fatigue life evaluation method，the finite element model of all-steel radial tire 295/80R22.5 was built.Parameters like strain，stress and strain energy density were obtained using ABAQUS implicit algorithm，and the tire fatigue life evaluation parameters were identified based on actual failure modes.The results indicated that，under long-lasting and high speed condition，the strain energy density and rebar tension force should be chosen as the tire fatigue life evaluation parameters，and appropriately increasing the thickness of the composite between 2# belt and 3# belt could lengthen the fatigue life effectively.Under the condition of overload and low speed，the shear stress between the cord and rubber compound should be chosen as the tire fatigue life evaluation parameter，and appropriately reducing the height of the carcass layers and reinforcement layers could lengthen the fatigue life effectively. |
