水轮发电机圆盘式转子支架挠度值的估算

Expressions of the Flexibility of Generator Circular Rotor's Spider

本文运用弹性力学板壳理论推导出了水轮发电机圆盘式转子支架的挠度值的估算公式,通过对已运行的数台机组的有限元计算结果的对比,考虑了构件的通风孔、腹板开孔及热打键等因素的影响,其结果表明估算公式有较高的准确性。

Based on the shell theory of elasticity mechanics, this paper presented a expressions to calculate the flexibility of circular rotor's bracket. In the expressions, we have given a coefficient ,which considered factors of the bbwhole and the hole on the shell hanging it and the rigidity on the keyway of it. After do these, the expressions should be correct.
