摘要

针对长叶片的特点，建立了正确反映叶片剪切作用的影响和形心、剪心及其沿叶高变化率等描述长叶片完整的空间扭曲梁有限元模型和分析方法。该模型和方法正确描述和反映了长叶片弯曲和扭转的耦合效应，具有更宽的适用范围和更高的计算精度。

Abstract

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.
