Real-time Vibration Control Of Rigid Rotors Using Controlled Supply Pressure Hydrostatic Squeeze Film Dampers

Résumé: the aim of this research is to study the Real-time control vibration of rigid rotor using controlled supply pressure hydrostatic squeeze film dampers. A linear model of the hydrostatic squeeze film damper has been developed in order to study the effect of the supply pressure on the dynamic behaviour of a rigid rotor. A new control system is proposed to reduce the transient response of the rotor using controlled supply pressure in order to control stiffness hydrostatic bearings. The results show that it is possible to effectively monitor the supply pressure and the dynamic characteristics of the fluid inside the hydrostatic squeeze film dampers for a better control of rigid rotor vibration and bearing transmitted forces.
