Abstract：

The loads on the internal parts of robot reducer are asymmetric periodic variable loads. Therefore, the robot manipulator was simulated by the inertia load component, and the fatigue life test technology of the robot reducer simulating the actual conditions was studied. According to the fatigue equivalent theory, the basic method of the accelerated fatigue life test was established by the fatigue life test device of the robot reducer, and the main factors affecting the test time of the fatigue life were analyzed. The results show that the moment of inertia affects the angular acceleration, which affects the optimal swing angle and position to affect the test time. Furthermore, the test time of the accelerated fatigue life test is optimized by optimizing the moment of inertia, angular acceleration, swing angle and swing position of the inertia load component, which provides theoretical support for the reasonable design of the fatigue life test device for the robot reducer.
