不平衡磁拉力作用下偏心转子的非线性振动OA北大核心CSCDCSTPCD
Nonlinear Vibration of an Eccentric Rotor Subjected to Unbalanced Magnetic Pull
用数值方法研究不平衡磁拉力、偏心力、陀螺力及极对数对发电机空载运行时转子振动的影响.结果表明,不平衡磁拉力可引起大幅度圆形涡动.
The effects of unbalanced magnetic pull ( UMP), mass eccentricity, gyroscopic forces and pole-pair number on the vibrations of an eccentric rotor in three-phase generator under no-load were investigated by means of the numerical method. It is concluded that UMP can cause large amplitude circular whirling.
