Gas foil bearing integrated with active magnetic bearing numerical modelling and analysis

Abstract

Gas foil bearings GFBs has been considered as an alternative to traditional bearings in recent turbomachinery industries However the applications of Gas Foil Bearings have been narrowed due to low damping and nonlinear characteristics Moreover the presence of sub synchronous and super synchronous frequencies introduces undesirable nonlinear effects to the system This necessitates a non conventional bearing system which can overcome all these shortcomings The current trend is to develop...
