Analiza dynamiczna ruchu wału obciążonego niesymetrycznie podpartego w dwóch łożyskach ślizgowych o zarysie niekołowym

Wojciech Niemotko

Abstract

In the dissertation the influence of the load asymmetry on the motion of the rotor supported in three-lobe bearings was examined. The regions of stable and unstable work of rotor were indicated. It was proved that in different exploitation and construction conditions the rotor reaction on the load asymmetry is also different. There are some edge values of exploitation and construction parameters that separate regions of different rotor reaction on the change of asymmetry coefficient. For these values of parameters the critical rotation velocity does not depend on the load asymmetry. For the research purpose the numerical simulation method was used.
