Patent attributes
A rotary fatigue tester with complex loads includes a pump, a first motor, a second motor, a circulatory loop, an experimental kettle body, and a holding device. The experimental kettle body is a cylindrical tank, the circulatory loop is located on the experimental kettle body, a pump is located within the circulatory loop and is connected with a corrosive gas pipeline; the holding device is located within the experimental kettle body for fixing a test piece, a force-bearing pole is located at one side of the experimental kettle body for applying a shear force to the test piece, the holding device and the force-bearing pole are connected with the first motor and the second motor respectively. The rotary fatigue tester is able to simultaneously apply the axial alternating load and tangential alternating load to the test piece, for simulating the force of the test piece under complex loads.
