| Abstract [eng] |
Doctoral dissertation consists of an introduction, four chapters, conclusions, list of cited sources and annexes. General volume of doctoral dissertation 141 pages, with 106 figures and 90 cited bibliographical sources. The first chapter of doctoral dissertation analyzes scientific periodicals and international standards of rotor dynamics and its relationship with the rotor elements of diagnosis. Intermediate conclusions presented at the end of section. The second chapter of doctoral dissertation dedicated to describe an analytical and generalized finite element model of vertical rotor. The section will also present the results of calculations. Intermediate conclusions presented at the end of section. The third section contains three independent experimental subsections. The first test described in the first subsection of this chapter. Subchapter dedicated to investigate and compare the vertical and horizontal rotor dynamics and its influence to rotor with rolling bearing diagnostics. Second subsection of this chapter dedicated to investigate a vertical and horizontal rotor with inner ring race fault of rolling bearing and variable dynamic imbalance force phase angle. The third subsection of this chapter dedicated to investigate a vertical rotor system with inclination angle from vertical. Intermediate conclusions presented at the end of section. The fourth section of this paper summarizes the vertical rotor finite element model verification. The chapter describes the experimental study, which was carried out with different radial gap having sliding bearings; the results are compared with the calculation results. Intermediate conclusions presented at the end of section. In the end of doctoral dissertation general conclusions, bibliographical references list, published scientific publications list, and annexes presented. |
