摘　　要：以双壳系统模型为水轮发电机定子系统的物理模型 ,建立了三相对称稳态运行状态下定子系统的磁固耦合振动方程·　分析了定子系统磁固耦合的双重共振 ,指出其响应具有跳跃现象 。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.
