Abstract

The invention discloses an online identification method for the rigidity and damping coefficient of a floating tile fluid lubrication bearing, relates to the field of rotor dynamics, and solves the problem that the rigidity and damping coefficient of the floating tile fluid lubrication bearing during rotor rotation are difficult to measure online by using the existing method. According to the method, the rigidity and damping coefficient of a corresponding structure are measured by performing a static loading test on a floating tile fluid lubrication bearing, and when a rotor works normally, the displacement of the rotor and a pivot in the vertical direction is detected; according to the displacement of the rotor and the tile in the vertical direction, the overall rigidity and the damping coefficient of the bearing when the rotor rotates are calculated through the method. According to the method, the dynamic coefficient of the floating tile fluid lubrication bearing under different rotating speeds of the rotor can be easily identified on line.
