Test system for reproducing load spectrum and fatigue of motorcycle frame in actual traveling

The utility model discloses a test system for reproducing load spectrum and fatigue of a motorcycle frame in actual travelling. The test system for reproducing load spectrum and fatigue of the motorcycle frame in actual travelling includes a linear guide rail, a horizontal vibration exciter driving the linear guide rail for loading a front holder of a motorcycle, a rear support connected with a wheel of a rear fork of the motorcycle, a vertical vibration exciter applying dynamic load simulating an engine and passengers in the front part and in the rear part on the motorcycle frame, a stress-strain sensor adhered on key points and weak points of the frame, a data collector, a controller and a computer. The stress-strain sensor is connected with the data collector. The data collector is connected with the controller. The controller controls the horizontal vibration exciter and the vertical horizontal vibration exciter. The computer is connected with the controller. By combining with stress conditions of the motorcycle frame in actual traveling and selecting a multi-point loading method and a force-controlling method, the test system for reproducing load spectrum and fatigue of the motorcycle frame in actual travelling reproduces load spectrum and fatigue of the motorcycle frame in actual travelling indoors accurately and efficiently.
