摘要
本文确定了水轮发电机定子系统的双壳模型．将梁函数组合法应用到求解双壳系统的固有特性，得到了双壳系统有电磁刚度项时的固有频率和振型．计算了额定对称运行状态下定子系统有电磁刚度项时的固有频率，给出了电磁刚度项对定子系统固有频率的影响．
A double shell model of a hydrogenerator stator system is established in the paper.A combination method of the beam function is used for obtaining the natural characteristics of the double shell system.The natural frequencies and vibration mode of the double shell system with electromagnetic stiffness are derived and the natural frequencies of the stator system with electromagnetic stiffness under rated operating conditions is computed,and the influence of the electromagnetic stiffness on the natural frequencies of the stator system is also presented.
