| Abstract: | 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. |
