摘要: This paper studies the nonlinear dynamic analysis of a flexible rotor supported by externally pressurized porous gas journal bearings. A time-dependent mathematical model for bearings is presented. The finite difference method and Successive Over Relation (S.O.R.) are employed to solve modified Reynolds' equation. system state trajectory, Poincare maps, power spectra, bifurcation diagrams used analyze behavior center in horizontal vertical directions under different operating conditions. reveals complex comprising periodic quasiperiodic response center. shows how this type varies with changes mass bearing number results study contribute further understanding dynamics gas-lubricated, pressurized, rotor-bearing systems.
