Mathematical modelling of a long squeeze film magnetorheological damper for rotor systems
Original language description
Lateral vibration of rotor systems can be efficiently reduced by damping devices included between the rotor and the stationary part of the rotating machine. To achieve their optimum performance the damping effect must be controllable. This is enabled bymagnetorheological dampers. Their damping depends on resistance against the flow of the magnetorheological liquid which can be controlled by the change of intensity of the magnetic field. This paper deals with the procedure for determination of the pressure distribution in the gap of a long squeeze film magnetorheological damper and with investigation of its behaviour by means of computational simulations. The results show that the developed model has all properties of real magnetorheological dampers observed during their operation.
