COMPLETE BENDING—TWISTING BEAM FINITE ELEMENT METHOD FOR ANALYZING STATIC AND DYNAMIC CHARACTERISTICS OF TURBINE LONG BLADE PART I MODEL[J]. Thermal power generation, 1997, (1): 49-56. DOI: 10.19666/j.rlfd.1997.01.014.
In accordance with the structure properties of steam turbine long blade. a complete bending—twisting beam finite element model and analysis method is set up
which indicates the shear effect and the variation of centroid and shear center along blade height. The model and method precisely describes the deflection characteristics of coupled bending and twisting of long blades. As a result the mentioned model and methed has greater adaptability and precision.
