Investigation of resonance frequencies of a rotor system with segmental sliding bearings

Abstract

This paper is based on investigation of self-vibrations of rotary systems with segmental sliding bearings, having different frequencies of rotor revolution. The graph of resonant frequencies of operating rotary system obtained from experimental investigation is given. It can seen how frequencies of rotation are unacceptable the worst working rotary system by this graph. The problem of this work is formulated, technical characteristics of primary elements of investigated system and operation principle are provided. Methodology of the experimental investigated is described. The obtained results are presented in graphs and a comparison of obtained results and its discussion are given. General conclusions are presented at the end of the work.
