Original abstract

One of the possibility , how to reduce amplitude of transversal vibration of rotors is to put together their rotating and no-rotating part by the squeeze film dampers. In this work is presented new access to analysis motion of the rigid body in the liquid. This access is based on Navier Stokes equation. Using the suitable substitution is possible to separate and solve motion of the numerical stability of the solution and influence geometrical parameters of the damper on the additional effects, which are include to the solution of the rotor systems.

Czech abstract

Jednou z možností jak snížit amplitudu příčného kmitání rotorů, je vložit mezi jejich rotující a nerotující část hydrodynamický tlumič. Tento systém se vzhledem ke kmitající hřídeli projevuje přídavnými účinky a to přídavnou hmotností a tlumením, jenž musí být zahrnuty do řešení rotorové soustavy. V tomto příspěvku jsou stanoveny tyto účinky pomocí nového přístupu, jenž byl vymyšlen a rozpracován na FSI VUT Brno a vychází z Navier-Stokesovy rovnice. Která umožňuje, užitím vhodné substituce, separovat od sebe pohyb tělesa a tekutiny.
