The design of rotating machines working in chambers submerged in liquids is a complicated technological problem. Vibration of the whole system produced by unbalance of the rotating parts can be significantly reduced if damping devices are inserted between the rotor and its stationary part. This is enabled by application of semiactive magnetorheological squeeze film dampers. Their damping is produced by squeezing a thin film of magnetorheological fluid between two rings and is controlled by the change of the magnetic flux passing through the lubricating layer. The investigating behaviour of such systems requires to analyse several mutually coupled physical problems (mechanical, hydraulical, electrical and magnetic).
