The Combined Internal and Principal Parametric Resonances on Continuum Stator System of Asynchronous Machine

Abstract: With the increasing requirement of quiet electrical machines in the civil and defense industry, it is very significant and necessary to predict the vibration and noise characteristics of stator and rotor in the early conceptual phase. Therefore, the combined internal and principal parametric resonances of a stator system excited by radial electromagnetic force are presented in this paper. The stator structure is modeled as a continuum double-shell system which is loaded by a varying distributed electromagnetic… Show more

“…The nonlinear vibration of stator and rotor system under eccentric air gap electromagnetic force has been widely concerned [4][5][6][7]. Multiple resonance is an important research direction in nonlinear vibration problems [3,8]. The characteristic of multiple resonance is that multiple modes are excited at the same time.…”
