Abstract: The wire rope is an important part of the traction system in the real vehicle crash test, which plays the role of transferring the traction force to the test vehicle. This paper first analyzes the structural characteristics of the wire rope, then lists the possible damage types of wire rope of traction system in the real vehicle crash test, and prepares the damaged wire rope samples for the test. Finally, according to the test results, the influences of different types of damage on the tensile properties and service life of wire rope of traction system in the real vehicle crash test are analyzed. The research on the fatigue damage of wire rope of traction system in the real vehicle crash test can eliminate the potential safety hazards, and is of great significance to ensure the safe production of the test.
