Modelling of magnetorheological oils in rotordynamic damping devices by bilinear material
Original language description
To reduce lateral vibrations of rotors excited by unbalance of the rotating parts the damping devices are added to the rotor supports. To achieve their optimum performance their damping effect must be controllable. This is offered by magnetorheological squeeze film dampers whose damping force is produced by squeezing a thin layer of magnetorheological fluid between two concentric rings. The damping element is equipped with an electric coil that generates magnetic flux passing through the lubricating oil. As its resistance against the flow depends on magnetic induction, the change of the current can be used to control the damping force. The development of a new mathematical model of a magnetorheological squeeze film damper is based on assumptions of theclassical theory of lubrication except that for the lubricant. Because the magnetorheological oils affected by a magnetic field belong to the class of liquids with a yielding shear stress, the lubricant is represented by a bilinear the-o
