Limit cycle of the self-excited oscillations of the rotor blades of a centrifugal compressor

Numerical and Analytical Modeling of Centrifugal Pump

“…They are especially often used in various cooling systems. The design and calculation of centrifugal pumps are fairly well studied and described in the literature [1][2][3][4][5][6][7][8][9]. When calculating such a pump and the hydrostatic bearing included in it ( Fig.…”

Hopf Bifurcation and Feedback Control of Self-Excited Torsion Vibration in the Drive System

“…Due to the variation of friction condition in the working interface, negative damping effect can be caused and lead to self-excited torsion vibration and instability in the drive system. In recent years, the self-excited vibration and Hopf bifurcation characteristics are broadly concerned by many scholars in different fields [3][4][5]. It is significant to study the existence and stability of self-excited vibration for revealing the bifurcation phenomena and controlling the vibration behaviors [6,7].…”
