Description

technical field [0001] The invention relates to the technical field of testing automotive electrical components, in particular to a wire harness fatigue testing device and testing method with high testing efficiency, good testing consistency and high testing precision. Background technique [0002] There are many wiring harnesses on the car, and the quality requirements for the wiring harnesses installed at two points with frequent changes in relative positions are higher. During the frequent and long-term work of the car, the wiring harness may be broken due to the aging of the wiring harness, causing safety hazards to the car . [0003] The wire harness fatigue testing device in the prior art has the disadvantages of low testing efficiency, poor testing consistency and low testing accuracy. [0004] Chinese Patent Authorization Publication No.: CN104374537A, the authorized publication date is February 25, 2015, which discloses an all-round wire harness fatigue test fixtur...
