Analysis of Oil Film Boundary Conditions of Tilting Pad Bearing Based on a Geometrical Model
摘要
Abstract
The geometric model describing the boundary conditions of tilting-pad bearings was studied. The coupling effect of the shaft axis, pad center and bearing center locations was analyzed to solve the Reynolds equation and analyze the film pressure distribution by means of finite difference method. Theoretical derivation indicates that the position of each pad is determined by preset parameters and the location of shaft center only. Numerical results show that the bearing capacity increases with the increase of the eccentricity ratio. A case study demonstrates that once the shaft center location is determined, the angle of displacement and the eccentricity ratio can be determined correspondingly, thus the dynamic equation of each pad can be solved. The feasibility law of the boundary conditions has been established, which provides a theoretical basis for the modeling of tilting pad bearings.关键词
