Original Abstract

Příspěvek se zabývá výpočtovou analýzou statických a dynamických vlastností hydrodynamických kluzných ložisek.

English abstract

This contribution deals with computational modelling of journal bearing analyses. In this contribution a new theoretical approach to the modelling of static and dynamic behaviour of the rigid rotating body in real liquid is presented. The approach is based on the application of Navier-Stokes motion eq., equation of continuity and boundary conditions eqs. It is possible to separate the motion of the rigid body and real liquid from each other using suitable transformation relations and then it is also possible to separate the stationary and nonstationary motions from each other. A method of control volumes is used for these analyses. The Real Bézier body is used for the description of the geometrical configuration and also for the approximation of velocity and pressure functions. The combined ALE (Arbitrary Lagrange-Euler) method is used, because it´s necessary to generate a new net (to perform new meshing) for a change of the shaft position. Some results of the numerical solution of the model task are presented in this contribution.
