Coupled Solution

Thrust bearing model is developed for fluid flow calculation and for determination of bearing integral characteristics in the presence of sliding surfaces closure and shaft angular displacements. The model is based on the coupled solution of the problem of incompressible fluid flow between the sliding surfaces and the problem of bearing and shaft elements deformation under the action of the fluid film pressure. Verification of the bearing model results is carried out by the comparison versus the fluid flow calculation results obtained by STAR-CD software and the experimental and theoretical results represented in the certain literature. Thrust bearing characteristics are determined versus sliding surfaces closure and rotating disk (runner) angular displacements. The contribution of the sliding surfaces deformations into bearing integral characteristics is estimated.

Dynamics Characteristic

A design, a mathematical model are presented and a calculation technique of quality indicators of the gas-static thrust bearing dynamics with the elastic suspended support center is described. It is shown that the application of such improvement allows to eliminate completely essential shortcomings of the quality of dynamics characteristic for a bearing with annular diaphragms and transforms the construction into a dynamic system with optimal dynamic characteristics – high indicators of degree of stability, aperiodic nature of the transient process, values of the oscillation index that are peculiar to ideally damped dynamic systems
