汽轮机叶片整圈结构设计应用中的几个问题

Some Problems of Dynamic Design of The Turbine Blade with Annular Tie

叶片整圈结构在提高汽轮机叶片工作可靠性方面具有突出优点,得到日益广泛应用。本文件对国内实际使用中的情况,论述了这种结构振动设计中值得注意的几个问题。

The annular lacing and shroud constraction formed a closed ring are widely used for the blade design. This paper describes the vibration behavior and good reliability of the blade of this construction. Some fundamental problems of dynamic design of the blade have been discussed in detail.
