Abstract

The present invention is stability judging and controlling technology for the rotor system of sliding bearing, and relates to the stability analysis, fault diagnosis and controlling technology of rotating machinery. Based on the energy conversion and conservation equation for bearing fluid-solid coupling motion, the present invention adopts the analysis method of vortex coupled excitation and non-linear coupled vibration displacement limit ring to control the effect of outside-system disturbance parameter, structural parameters and physical parameters on the sliding bearing subsystem effectively, to regulate the coupling kinematic characteristics of shaft neck rotation angular speed, shaft neck vortex angular speed and eccentricity varying speed reasonably and to ensure the energy conversion and conservation equation not smaller than 1.

Description

technical field

[0001] The invention relates to stability analysis, fault diagnosis and control methods of rotating machinery. Background technique

[0002] At present, with the development of rotating machinery in the direction of high speed, large span, and flexible light structure, the stability problem caused by the interaction between the oil film of the sliding bearing and the rotor has become increasingly prominent. solved puzzles.

[0003] In engineering practice, there has not been a practical method and standard for the stability criterion of the sliding bearing rotor system in the field of rotating machinery. Effective diagnosis and control are carried out in order to ensure the stability of operation. Therefore, equipment damage accidents of rotating machinery often occur. Contents of the invention

[0004] In engineering practice, a method of judging the stability of the sliding bearing rotor system based on the bearing capacity is proposed, that is, when th...
