Description
| - Článek se zabývá numerickým postupem pro zkoumání rázů rotorů uložených v dlouhých kavitovaných kapalinných ložiskách na stacionární část. (cs)
- The rotor systems consit of two principal components, of a rotor and of a stationary part, and the fluid film bearings are often used as coupling elements. As the clearance between the discs and the casing is usually very narrow, excessive lateral vibration of the rotor can produce impacts between the discs and the housing. Because up to now influence of the fluid film bearings and the impacts on the rotor behaviour has been investigated separately, it is desirable to develope a procedure which would make possible to analyze their mutual interaction. Into the mathematical models both the hydrodynamic bearings and the contacts are implemented by means of nonlinear force couplings. To determine the contact forces a Hertz theory is applied. The hydrodynamic forces depend on the pressure distribution in the oil film. As the bearing gap is very narrow a classical theory of lubrication can be used for this purpose. If pressure at some location of the bearing gap should drop below a critical level, a vapour
