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 lateral vibrations of rotors produced by unbalance of rotating parts consists in adding damping devices to the rotor supports. Their damping effect must be controllable to achieve their optimum performance. This is enabled by magnetorheological squeeze film dampers. In the developed mathematical model the number of the rotor system state parameters is reduced. The steady state solution of the equation of motion is calculated by the trigonometric collocation method. Modelling the magnetorheological oil by bilinear material, determination of the hydraulic damping forces by means of the Reynolds equation adapted to bilinear material, reduction of the rotor system utilizing the influence coefficients determined by the finite element method, and learning more on suppressing the lateral vibration of flexible rotors by magnetorheological squeeze film dampers are the principle contributions of this article. Reduction of the amplitude of the rotor vibration as a result of controlling the damping force in the supports according to the angular speed was confirmed by computer simulations. © Springer International Publishing Switzerland 2017.
