A COMPUTATIONAL STUDY OF EFFICIENCY OF CONTROLLABLE SEMIACTIVE MAGNETORHEOLOGICAL DAMPERS REDUCING LATERAL VIBRATION OF ROTORS WORKING IN CHAMBERS SUBMERGED IN LIQUIDS

Popis výsledku v původním jazyce

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. Due to variable operating conditions depending on the depth of the chamber submerging to achieve their optimum performance, the damping effect must be controllable. 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 liquid, in which the chamber is submerged, is considered as incompressible and acts on the chamber walls by its inertia and damping effects. The investigating behaviour of such systems requires to analyse several mutually coupled physical problems (mechanical, hydr
