The Steady State Response of Multi-disc Rotors Damped by Magnetorheological Squeeze Film Dampers

Popis výsledku v původním jazyce

A frequently used technological solution for suppressing lateralnvibrations of rotors produced by unbalance of rotating parts consists innadding damping devices to the rotor supports. Their damping effect must bencontrollable to achieve their optimum performance. This is enabled bynmagnetorheological squeeze film dampers. In the developed mathematicalnmodel the number of the rotor system state parameters is reduced. Thensteady state solution of the equation of motion is calculated by thentrigonometric collocation method. Modelling the magnetorheological oil bynbilinear material, determination of the hydraulic damping forces by meansnof the Reynolds equation adapted to bilinear material, reduction of thenrotor system utilizing the influence coefficients determined by the finitenelement method, and learning more on suppressing the lateral vibration ofnflexible rotors by magnetorheological squeeze film dampers are thenprinciple contributions of this article. Reduction of the amplitude of thenrotor vibration as a result of controlling the damping force in thensupports according to the angular speed was confirmed by computernsimulations.n
