Abstract

Seal and bearing characteristic is an important factor affecting the performance of the rotor system. The non-linear dynamic behaviours of a rotor-bearing-seal coupled system are investigated. Dynamic trajectories, Poincaré maps, largest Lyapunov exponents, frequency spectra, and bifurcation diagrams which are applied to analyse the features of the rotor-bearing-seal system in various parameters. Various non-linear phenomena in the rotor-bearing-seal system, such as periodic motion, double-periodic motion, multi-periodic, and quasi-periodic motion are investigated. The results of this study may contribute to a further understanding of the non-linear dynamics of such a rotor-bearing-seal coupled system.
