Vibration characteristics analysis of mistuned bladed disk system based on mobile interface prestressed CMS super-element method
A new mobile interface prestressed component mode synthesis (CMS) super-element method is proposed with the mobile interface prestressed and free interface super-element approach. Analysis accuracy of this method is verified by the cyclic symmetry analysis method and the direct method. The mistuning...
