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 ,在某些参数域上有多解共存现象
The double-shell system model is taken as the physical model of the hydrogenerator stator system, and the three-phase symmetric steady-state coupled vibration equation of the stator system is established. The double resonance of the stator-system magnetic-solid coupling is analyzed. Jump phenomenon, in some parameters of the field how to coexist
