The paper contains a study of mutual interactions, which occur between lateral, torsional and axial vibrations in multi-supported rotors operating in the non-linear range. The methods of modelling of the selected defects have been presented (e.g. rotor cracs and bearings misalignments). These defects have been regarded as the factors generating the coupled forms of vibrations. In the paper a part...
In the research conducted has been an assesement on the influence of the labyrinth seals in the 13K215 turboset on the dynamic properties of the machine working under stable conditions, as well as when there was a reduction in the systems stability margin. The existing complex and nonlinear model of the 13K215 turboset and the application software for the model's dynamic investigation were used, coupling...
