Originální abstrakt

Příspěvek se zabývá výpočtovým modelováním dynamických vlastností kluzných ložisek. Při analýze se využívá Navier Stokesova rovnice. Pro popis objemu vyplněného tekutinou i pro aproximaci řešení se využívá Beziérovo těleso.

Anglický abstrakt

This contribution is focused on the interaction of rigid body with thin fluid layer. Long and short, cavitating or noncavitating journal bearings can be some technical applications. Governing equations for this analysis are the Navier Stokes eq., continuity and boundary conditions. Theoretical base of a new approach to the analysis of dynamic behavior of nonstationar analysis in time and frequency domains is presented. This totally new approach is based on separation of shaft and liquid layer from each other. It is possible to determine, using this separation, the database of additional effects of fluid film, such as function only of one shaft parameter, which can be a shaft center position. The Bézier body is used for the approximation of geometrical configuration and also for approximation of solution such as velocities and pressures. Method of control volumes is used by solution. Curvilinear co-ordinates are used by description of geometrical configuration and perpendicular co-ordinates are used by solution of velocities and pressures
