Active squeeze film dampers in rotordynamics

2001
Summary: Electro-rheological and magneto-rheological fluids react to electric and magnetic fields respectively undergoing changes in their mechanical characteristics, viscosity and stiffness in particular. Their macroscopic behaviour is represented by the Bingham plastic model.

Simple but Accurate Models for Squeeze-film Dampers

2007 IEEE Sensors, 2007
Simple but accurate compact models are derived for squeeze-film dampers having rectangular areas and vibrating in translational or in torsion motion. First, shape functions are derived that enable fast and accurate calculation of the low squeeze number damping coefficient for any aspect ratio of the damper surface. Next, a series-form approximation for

Classical control of a magnetorheological squeeze film damper

2005
An adaptive squeeze film damper is one whose properties can be continuously adapted to minimize the amplitude of vibration of the rotor in any working condition. This paper concerns an adaptive squeeze film damper with a magnetorheological fluid (MR): a change of its apparent viscosity and stiffness is obtained by applying a magnetic field through the ...
