A Parametric Study of the General Profile for Hydrodynamic Journal Bearings

Abstract:

Study on bearings profiles is one of important factors in the hydrodynamic bearings shape optimization. In order to build a unity shape optimization model, the study on the general profile of hydrodynamic journal bearings was proposed. Firstly, the geometrical theory was studied. Secondly, four kinds of general profiles based on points, Taylor series, Bezier curve and Fourier series were introduced. Thirdly, analyzed and compared with the four kinds of general profiles, the general profile based on Fourier series was proved to be the most suitable to set up the unity shape optimization model. The general profile breaks through the performance limitation of that formed by the inherence characteristics of mathematical model of the known bearing, which not only integrates existing profiles but also develops some other new arbitrary profiles. The shape optimization can be realized by taking coefficients of the general profile as design variables.
