摘　　要：在分析成组叶片振动特点的基础上，提出了一个适用于蒸汽轮机成组叶片的气动弹性模型，应用该模型对某型成组叶片的气动弹性稳定性进行了分析。In order to analyze aeroelastic stability of grouped blades of a steam turbine,an aeroelastic model has been developed.The aeroelastic stability of the grouped blades of a given steam turbine has been predicted by means of the present model.The results i ndicate that the aeroelastic stability o f the blades located at the middle of a blade group is better than that of the blades located at its edge.
