摘要
建立了轮胎断面模型和三维有限元模型,模拟了轮胎稳定滚动时断面上各部件橡胶材料的负荷情况。基于橡胶疲劳裂纹扩展理论和临界平面法,计算了轮胎模型滚动情况下橡胶材料的疲劳寿命,并研究了轮胎橡胶材料疲劳寿命随负荷的变化情况,同时比较了不同负荷下轮胎各部件橡胶材料疲劳危险点的分布。
A 3D tire model was established along with the tire cross-section model,and the load of each rubber component under steady rolling condition was calculated. The fatigue analysis of rubber components of tire model under rolling was conducted based on fatigue crack propagation theory and critical plane approach.The influence of load conditions on the fatigue life of rubber components was analyzed,and the distributions of critical fatigue points in different rubber components were compared under each load condition.
