摘　　要：为解决高压线束反复弯曲引起的疲劳失效问题,结合工业路径解决方案(IPS)柔性布线仿真软件、ABAQUS有限元计算软件、Fe-Safe疲劳寿命计算软件建立柔性管线布线模型,计算导线弯曲过程中各部位应力变化,绘制疲劳寿命分布云图。仿真结果表明:导线反复弯曲过程中,固定卡扣处导线所受应力较大、疲劳寿命较低;导线线芯外层应力水平较内层高,对应疲劳寿命较低。利用振动台开展疲劳寿命试验,试验结果与仿真结果均表明:在一定范围内,适当增加固定点间导线长度,可延长导线的弯曲疲劳寿命。In order to solve the issue of fatigue failure caused by repeated bending of high-voltage harness,the flexible pipeline wiring model was established,and the stress change and fatigue life distribution cloud map of each part in the process of wire bending were calculated based on IPS flexible wiring simulation software,ABAQUS finite element calculation software and Fe-Safe fatigue life calculation software.The simulation results show that,in the process of repeated bending,the stress of the wire at the fixed points is high and the fatigue life is low.The stress level at the outer layer of the wire core is higher than that of the inner layer,and the fatigue life is lower.The bending fatigue life test of wire was carried out by using vibration table.Both the test results and the simulation results show that the bending fatigue life of the wires can be prolonged by appropriately increasing the length between the fixed points within an appropriate range.
