汽轮机转子T形叶根轮缘强度补充分析

Strength Supplementary Analysis of T-shaped Blade Root/Wheel Flange of Steam Turbine Rotor

文章对T形叶根轮缘强度在《火力发电设备技术手册》要求的经典强度计算基础上进行了补充分析,得出了在一定结构尺寸下其最大应力截面并不是常规计算的那几个计算截面的结论,并提取了能满足工程计算需要的该截面计算公式。

Based on the classical strength calculation required by ＂Technical Manual of Thermal Power Equipment＂, the strength of T-shaped blade root / wheel flange is supplemented and analyzed in this paper. It is concluded that the maximum stress section of the structure is not the same as that of the conventional calculation by a certain size of the structure, and the calculation formula of this section which can meet the needs of engineering calculation is extracted.
