• STATIC AND DYNAMIC CHARACTERISTICS OF FINITE EXPONENTIAL FILM-SHAPED SLIDER BEARINGS LUBRICATED WITH NEWTONIAN FLUID

Abstract

Analysis of dynamic characteristics plays an important role in designing hydrodynamic bearings. The analysis of dynamic characteristics for a finite slider bearing with exponential film profile is presented by taking into account the bearing squeezing action. The detailed analysis is presented for exponential film-shaped finite slider bearings by using perturbation technique. Two types of Reynolds equations pertaining to steady performance and the dynamic characteristics are obtained. The closed form solution of these equations is obtained by Numerical methods. Increasing values of aspect ratio (width-to-length ratio) enhances the pressure performance. Comparing with those of plane slider bearing, the exponential shaped slider bearing provides the higher values of load carrying capacity, stiffness coefficient and damping coefficient.
