Abstract :
Purpose- The objective of this paper is to conduct a theoretical analysis of wide composite slider bearings of diverse film shapes like parabolic, plane, exponential, and secant for the case of couplestress fluid in the existence of magnetic field applied normal to bearing surface and on the basis of roughness of the surface. Design/Methodology – The generalised stochastic Reynolds equation is derived based on Stokes model and Christensen stochastic model. The expressions for the characteristics of bearing are obtained for general lubricant film shape in integral form and are numerically computed for the shapes under consideration. Findings- It is fascinating to note that the impact of magnetic field, couplestress and roughness of surface significantly affect the bearing characteristics. It is concluded from comparison that load supporting capability of parabolic slider is more significant. Originality/value – It is expected that these analyses will help design engineers to choose proper shaped slider bearings with appropriate couplestress, roughness parameters in the occurrence of applied magnetic field, which improves the normal functioning of the bearings.
