| Abstract: | Theoretical calculation and analysis about the high damping frequency of the last stage blades was tan＇led out by FEM. Based on the research of theory and experiment,a study on the relationship between the frequency and structure （shroud and lacing）was carried out,which was aimed at the special structure of the high damping last slage blades. And a practical and feasible method about adjusting frequency was proposed. |
