Deformations of a piezo?actuated bearing ring in journal bearings

An elastically deformable bearing ring is investigated. The piezo-actuated shaping of the elastic as well journal motion are coupled and determine height lubrication gap which takes a crucial part in theory hydrodynamic lubrication. influence active-dynamic on rotor dynamic behaviour has been investigated [1], especially for two-lobe bearing. present investigations aiming at active-static ring, i.e. finite number piezo actuators used to cause deformations ring. Moreover, realisation different shapes by introduced examined, whereas desired not necessarily limited geometries.
