【摘要】：由于静力隐式有限元算法很难准确模拟车轮径向疲劳试验,着重研究用动力显式有限元算法进行模拟的方法。论文详细介绍了车轮有限元网格、材料性能参数、轮胎简化、螺栓预紧、焊缝设置、转鼓转动、径向力加载等过程的设置方法及注意事项,列出车轮应力及表面压力的分布,提出判断分析结果合理与否的方法,最后详细介绍材料S-N曲线的选择方法,并对有限元分析及试验寿命结果进行比较,该动力显式模拟设置方法可得到较理想的分析结果。
[Abstract]:Because the static implicit finite element method is difficult to accurately simulate the wheel radial fatigue test, the simulation method is mainly studied by the dynamic explicit finite element method. This paper introduces the method of setting wheel finite element mesh, material properties, tire simplification, bolt pretension, weld setting, drum rotation, radial force loading process and the matters needing attention, list the distribution of wheel stress and surface pressure, put forward reasonable judgment analysis results and whether the selection method is introduced in detail the material S-N curve, and the finite element analysis and test results are compared, the dynamic explicit simulation setting method can get ideal results.
