Stabilizing Internal Damping in Hydrodynamic Bearings using Elegant Control Strategies

Abstract

The implementation of elegant control strategies to stabilize the internal damping problem in hydrodynamic bearing has been proposed in this paper. This implementation deals or gives an advantage of good stability of hydrodynamic bearing, even at critical or threshold speeds where an unstable whirl occurs leading to instability assisted greatly by this internal damping factor. Related stability graphs have been plotted using MATLAB 2013 and models have been designed using SIMULINK.
