摘　　要：主要研究用于轿车后桥耐久性试验载荷谱的优化处理方法。根据材料的低载强化特性,综合考虑了无效载荷的评价原则,既有效地保存了具有损伤效果的大载荷,又保存了具有强化效果的小载荷,避免了以往只要是小载荷就全部删除的误区,使得台架模拟更加接近实际的疲劳寿命。This paper studies the optimization methods of durability load spectrum of a car rear axle. Based on the material properties of the low load strengthening, we considered the evaluation principle of invalid load. It preserved not only high load which caused damage, but also could preserve the low load which has strengthening effect. It avoided misunderstanding about deleting all of the low loads. The test rig simulation will be closer to the actual fatigue life.
