| 摘 要： | 针对履带车辆悬挂系统关键部件-扭力轴的疲劳寿命预测技术展开研究,首先利用机械系统动力学仿真软件ADAMS建立了悬挂系统多刚体动力学模型, 应用模态集成方法在悬挂多刚体模型中集成扭力轴柔性体,通过添加约束与载荷边界条件,建立悬挂系统刚/柔体耦合模型。通过对典型工况的仿真计算,可以得到扭力轴上每个节点的载荷时间历程与应力时间历程,结合扭力轴的材料特性,并考虑应力集中系数、平均应力修正等各种影响因素,实现悬挂系统扭力轴疲劳寿命的预测。最后将实验结果同仿真结果进行了比较,得到了具有工程意义的结论。

| Abstract: | In allusion to the fatigue life of tracked vehicle torsion bar, virtual prototype model of tracked vehicle suspension system including flexible torsion bar is built on base of dynamic simulation software--ADAMS. Node force and stress results of the torsion bar from the final step simulation are acquired; taking into account of material characteristic and influence factors, fatigue life of the flexible body of torsion bar is predicted. Engineering results can be acquired through the comparison of the result of virtual test and statistical fatigue. |
