| description | In this paper, an investigation has been made to study the dynamic characteristics of porous inclined slider bearing with rough surface lubricated with micropolar fluid lubricant. On the basis of Eringen’s micro-continuum theory, the Reynolds type equation of porous slider bearing is derived by considering rough surface and squeezing action to evaluate dynamic characteristics of slider bearing. Perturbation method has been used for detailed analysis. Reynolds type equations are obtained for steady performance and perturbed characteristics. The solutions of these equations are obtained. According to the results, an increase (decrease) in the load carrying capacity, dynamic stiffness and damping coefficient are observed for the negatively (positively) skewed surface roughness. |
