| Abstract: | A double_shell model of hydroelectric_generator stator system was established. Applying the theory of mechano_electric analytical dynamics theory, the nonlinear vibration equation of magnetism and solid coupling of hydroelectric_generator stator system, under steadily balanced three_phases operating condition, was obtained. According to the method of multiple scales for nonlinear oscillations, the double resonances of magnetism and solid coupling of hydroelectric_generator stator system were investigated. It is pointed out that the system has abundant dynamics phenomenon including the attendant jumps and coexistence of multiple stable motions. |
