Abstract

The paper contains a study of mutual interactions, which occur between lateral, torsional and axial vibrations in multi-suported rotors operating in the non-linear range. The methods of modelling of the selected defects have been presesnted (e.g. rotor cracks and bearing misalignments). These defects have been regarded as the factors generating the coupled forms of vibrations. In the paper a [art. of work devoted to the influence of circumferential lecation of the crack and kinetostatic and dynamic rotor deflection line on the system dynamical response has been presented. Applicability of coupled and phase vibration are generally a result of different kinds of coupling taking place in the system and interactions between construction and material imperfections. Presented here as example can be rotor cracks and misalignment of the rotor line.
