摘要

运用壳体理论对 5 15 0 1型汽轮机汽缸壁开裂处的内压应力和热应力进行分析计算

并对裂纹的安全性进行了评定

根据计算结果对汽缸缺陷和汽机运行提出了建议。分析认为

该汽缸裂纹是安全的

不会发生一次性脆断。但该裂纹的应力强度因子k1值已接近断裂判据值

故消除缺陷可提高汽缸运行的安全性

Abstract

Applying shell theory

the internal pressure stress and the thermal stress of the cracked part on cylinder wall in a 51-50-1 type steam turbine have been analysed and calculated

and the safety of cracks being evaluated. At the same time

some recommendations for the cylinder defects and the steam turbine operation have been suggested. It is considered from analysis that the said cracks are safe

that is to say a single-stage brittle fracture can not occur.
