大型透平机组轴系扭曲临界转速的计算方法

Calculation Method of Torsional Critical Speed for Shafting Train

介绍了用霍尔茨(Holzer)法计算复杂轴系扭曲临界转速的具体简化方法,列举出几种典型几何结构的等效直径计算公式。用此方法编写的计算机程序可以计算任何一个大型复杂轴系。

The concrete simplied method of a complex shafting train is introduced by using Holzer to calculate the torsional critical speeds of a shaft train. Calculation formaular of equivalent diameters are listed for a few typical deometries. Complex shafting trains can be calculated by a computer programme with this method.
