Effect of Magnetohydrodynamics and Couple Stress on Steady and Dynamic Characteristics of Plane Slider Bearing

Abstract

In this paper, an attempt has been made to study the effects of MHD and couple stress fluid lubricants on the steady state and dynamic behaviour of plane slider bearings by considering the squeezing action. The modified Reynolds equation is derived for the plane slider bearing with squeeze effects for the MHD and couple stress fluid. The dynamic stiffness and damping characteristics of one-dimensional MHD and couplestress plane slider bearings are computed. The effect of MHD and couple stress fluid lubricant improves the steady state and dynamic stiffness and damping characteristics of the plane slider bearings.
