Abstract

Precise modelling of dynamics of complex technological systems is complicated problem requiring significant human and computational resources. Therefore, aiming to create model of rational size and complexity, some adjustments of models should be done applying experimentally obtained parameters of rotary systems and their elements.
This paper presents results of modelling of vibrations of rigid rotor caused by the degradation of hydrodynamic bearings. Model is composed applying equations of nonlinear hydrodynamic forces and measured parameters of a real rotary machine.
