A 2D Mathematical Model of a Short Magnetorheological Squeeze Film Damper Based on Representing the Lubricating Oil by Bilinear Theoretical Material

Popis výsledku v původním jazyce

Unbalance is the principal source of excitation of lateral vibrations of rotors and of increase of the time varying forces transmitted to the rotor casing. These undesirable effects can be reduced if the damping devices are inserted between the rotatingand stationary parts. To achieve their optimum performance in a wide range of rotational speeds their damping force must be adaptable to the current operating conditions. This is offered by application of magnetorheological damping elements. To learn more on their properties a new 2D mathematical model of a short magnetorheological squeeze film damper has been developed and is presented here. The model is based on representing the magnetorheological oil by bilinear material whose flow curve is continuous unlike to the models based on Bingham or Herschel-Bulkley theoretical fluids. This reduces the nonlinear character of the motion equations and increases computational stability of the procedures used for their solving which was confirme
