Analysis on Active Hydromagnetic Journal Bearing using Ansys

Abstract

In this study Active hydromagnetic journal bearing is designed and analysed by using ANSYS tool. Active Hydromagnetic journal bearing is a combination of Hydrodynamic journal bearing & Active magnetic bearing. We know that hydrodynamic journal bearing used to low speed and high load carrying capacity & its drawback is at high-speed shaft surface is come in contact and there wear also happen. In this condition hydrodynamic bearing also damages from contaminants as dirt or ash, also in the rise in temperature. In the active magnetic bearing is used to high speed and low load carrying capacity. When increasing load carrying capacity of active hydromagnetic bearing, it also increases design of active hydromagnetic bearing. When combining Hydrodynamic journal bearing & Active magnetic bearing it reduces drawback of both bearing. It working on high speed and high load carrying capacity. When combining both bearing considering main parameter is clearance in hydrodynamic journal bearing & Air gap in active magnetic bearing.
