Description
technical field [0001] The invention belongs to the field of experimental equipment, in particular to a rotor-bearing experimental platform. Background technique [0002] With the rapid development of the economy, the application of machines in various industries is becoming more and more extensive. Among all kinds of machines, more than 80% of the machines have rotor bearing systems. The working state of the rotor-bearing system directly affects the running state of a piece of equipment. [0003] Rotor-bearing system failures occur frequently and in different forms. Once equipment failure occurs, it will affect production and reduce enterprise benefits, and cause personal and property safety accidents. Mechanical fault diagnosis technology can detect equipment faults in advance in industrial production, prevent production stoppages and major accidents. Therefore, building a rotor-bearing test bench and studying the problem of rotor-bearing system fault extraction are ver...
