Outline
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.
