| Abstract: | Employing 3D 8node non harmonic finite element model , a method to analyze the vibration characteristics of steam turbine bladed group is developed based on the modal synthesis method . The numerical results of analysis of the bladed group with two lacing wires are very precise .It shows that the method developed in this paper has not only theoretical significance ,but engineering application value as well. |
