Abstract

The invention discloses an electric direct-drive shaft torsional fatigue test device and method, and aims to overcome defects of high cost, poor universality and oil leakage risk of an existing hydraulic fatigue test machine. The device comprises a mounting platform, a power direct-drive main motor, a power direct-drive auxiliary motor, a torque sensor and a connecting seat for clamping a test piece, wherein a movable sliding plate is mounted on the mounting platform, the power direct-drive main motor is rotatably mounted on the sliding plate, the power direct-drive auxiliary motor is rotatably mounted on the mounting platform, the connecting seat is movably mounted between the power direct-drive main motor and the power direct-drive auxiliary motor, the connecting seat is arranged betweenthe power direct-drive main motor and the power direct-drive auxiliary motor, and the torque sensor is arranged between the connecting seat and the power direct-drive main motor. The electric direct-drive shaft torsional fatigue test device is simple in structure, low in cost and good in universality, and the risk of oil leakage is avoided.

Description

technical field [0001] The invention relates to a fatigue test device, more specifically, it relates to an electric direct drive shaft torsion fatigue test device and method. Background technique [0002] Traditional torsional fatigue equipment mostly adopts hydraulic servo drive mode. This type of equipment needs to be equipped with auxiliary equipment such as hydraulic stations. The overall structure is relatively complicated and the efficiency is not high, and the energy consumption is relatively large. In addition, during the testing process of the hydraulic fatigue testing machine, the hydraulic oil is mixed with mechanical impurities and corrosive substances due to long-term use, resulting in the oil film strength of the hydraulic oil being insufficient to withstand the pressure of the working load, causing the metal surfaces to contact each other, resulting in friction. The force increases sharply, which accelerates the embarrassment of the parts, and the lubricating ...
