Simulation Test Stand For Oil Film Failure Mechanism Research Of Plain Bearing
1. The basic structure of the test bench
The test bench uses a motor, a dynamic torque sensor, a sliding bearing rotor system, and a hysteresis brake as the experimental load to form a complete fault simulation system. The size of the experimental load is changed by adjusting the excitation current of the hysteresis brake. Supporting data acquisition system and related software, acceleration sensor, eddy current sensor, etc. can realize the measurement of vibration, noise, torque and speed signal of rotor fault.
2. Experimental research content
Sliding bearing fault research: sliding bearing oil film instability fault, sliding bearing wear, special-shaped oil dynamic bearing, etc.;
Rotor fault research: rotor unbalance fault, rotor misalignment fault, rotor friction fault, rotor crack fault, rotor deformation fault, etc.;
Simulation of different working conditions: rotor and bearing characteristics under the state of motor speed up and down, rotor and bearing characteristics under different load conditions, etc.
