Static Frequency Test and Research of Steam Turbine Blades with Damp Structure Round Linking

This paper briefs the static test method of vibration frequency of steam turbine blade system with damp structure round linking,nodal diameter static frequency evaluation of first harmonic system vibration band of blades with round linking,high frequency vibration band nodal diameter frequency evaluation of blade system with round linking (including varbns damp structures),the danger of vibration band nodal diameter statie frequency falling in resonance of blades with damp structure round linking and the test and research results of handling thinking;and gives the safety evaluation indexes of nodal diameter static frequency of first harmonic system vibration band of blades with round linking.All these have reference value for judging the high frequency vibration of blade system.
