Multi-degree-of-freedom wire harness fatigue test equipment and fatigue test method thereof

The invention discloses multi-degree-of-freedom wire harness fatigue test equipment and a fatigue test method thereof. Existing dynamic wire harness applicability and service life simulation analysisthat multiple single-degree-of-freedom are simulated and then accumulated, and a test result is greatly different from a multi-degree-of-freedom automatic combination condition. A cable height detection mechanism comprises an infrared emitter and an infrared receiver, the infrared emitter and the infrared receiver are respectively driven by a vertical moving linear module to move up and down, andsupporting seats of the two vertical moving linear modules and two longitudinal guide rails respectively form sliding pairs; the transverse moving mechanism is driven by the vertical moving mechanismto move up and down; the longitudinal moving mechanism and the transverse moving mechanism are each provided with an angle adjusting assembly. In each angle adjusting assembly, a deflection mechanismis arranged at the top of a
