Abstract

The invention discloses a vibration transmission test bench for a magnetorheological damper controlled gear box shaft system, comprising a test bench, a motor, a first rotating shaft, a second rotating shaft, a first gear, and a second gear. A test device is arranged on one side of the first rotating shaft, and a test device is arranged on one side of the second rotating shaft. The first gear fixedly sleeves the first rotating shaft. A first magnetorheological damper is arranged at the bottom of the first rotating shaft. The second gear fixedly sleeves the second rotating shaft. A second magnetorheological damper is arranged at the bottom of the second rotating shaft. The first gear and the second gear are connected by means of meshing. According to the vibration transmission test bench for a magnetorheological damper controlled gear box shaft system, the vibration of a gear box body can be monitored, and the currents of the dampers can be changed in a timely manner to adapt to different working conditions of the gear box body, such as vibration change in the process of speed change or unbalanced vibration increase caused by wear. Thus, it is ensured that the vibration of the box body and the transmission shaft is kept at a low level.

Description

technical field [0001] The invention belongs to the technical field of application of magnetorheological dampers, and in particular relates to a vibration transmission test bench for a magnetorheological damper to control the shafting of a gear box. Background technique [0002] The magnetorheological damper is a kind of vibration-reducing and energy-dissipating device that uses the smart material—magnetorheological fluid as the working medium, and changes the viscosity of the magnetorheological fluid by loading a magnetic field to achieve adjustable damping force. Its outstanding features are mainly With good controllability, simple structure and low energy consumption, it is an ideal device for semi-active control of structural vibration, and has been widely used in various fields. [0003] Due to its compact structure, high efficiency, and reliable operation, gear transmission is widely used in automobiles, ships, aerospace and other fields. However, due to factors such ...
