Performance of magnetic fluid based circular step bearings

Abstract

Efforts have been made to analyze the perform-ance of a magnetic fluid based circular step bearing. The concerned Reynolds equation is solved with appropriate boundary conditions to obtain the pressure distribution which in turn, is used to get the load carrying capacity leading to the calculation of response time. Results are presented graphically. This investigation reveals that the performance of the bearing system gets enhanced consid-erably owing to the presence of the magnetic fluid. Further, it is observed that the radii ratio has a strong effect on the performance of the bearing system. In addition, this inves-tigation makes it clear that a performance of the bearing system can be enhanced substantially by choosing suitable values of the magnetization parameter, radii ratio and the supply pressure.
