摘　　要：通过收集资料 ,将历史上汽轮机扭叶片三种计算模型各自特点分别列出 ,指出了三种模型的优缺点及适应范围 .并从合理模化叶片、提高计算精度的观点出发 ,认为三维有限元模型将成为汽轮机扭叶片振动特性研究的重要手段 .Twist blade in steam turbine is studied mostly ,and the vibration feature is the focus. The thesis listed three calculation models of twist blade in steam turbine and described the sadvantages & disadvantages and the applied field of each one by collecting information. In order to make the model and the calculation better, it is proved that three-dimension finite element model would become an important method for studying the vibration feature of twist blade in steam turbine.
