VIBRATION EQUATION FOR GENERATOR ROTOR IN DUAL RESONANCE CASE WITH UNSYMMETRICAL LOAD
Generator rotor is a flexible stuff with approximately equal horizontal and vertical stiffness. Its natural frequency falls into two parts when the loads exerted on generator rotor are asymmetrical. Dual resonance phenomenon appears based on the former single frequency vibration. According to the variation of magnetic energy
differential equation of dual resonance was gotten by means of calculus of variation in this paper.
