Abstract :
Effects of couple stress and Magneto-hydrodynamics on a secant slider bearing are discussed in the present study. The basis of this discussion is the theory of couple stresses introduced by Stokes. Basic equations of motion are solved to derive pressure generated in the fluid and load carrying capacity of the bearing. Dynamic characteristics like damping coefficient and dynamic stiffness are also derived. Dynamic characteristics and the bearing performance, when squeezing is nil are evaluated by assigning some numerical values to the parameters. These results are illustrated graphically. It is concluded that the bearing characteristics, both steady and dynamic, will show an increasing trend in its values, when magnetic field is applied to the bearing structure and when fluids having couple stress are used to lubricate it.
