大直径、薄壁管道的载荷条件复杂,对其进行强度校核和稳定性分析非常必要.本文采用ANSYS有限元软件对某电厂余热利用工程引接的汽轮机排汽管道进行了强度和稳定性分析.计算结果表明:ANSYS有限元分析方法与CAESAR II软件相比,能更准确地反应管系局部应力分布情况,对大直径薄壁管道的优化设计及安全校验有很好的辅助作用.
大直徑、薄壁管道的載荷條件複雜,對其進行彊度校覈和穩定性分析非常必要.本文採用ANSYS有限元軟件對某電廠餘熱利用工程引接的汽輪機排汽管道進行瞭彊度和穩定性分析.計算結果錶明:ANSYS有限元分析方法與CAESAR II軟件相比,能更準確地反應管繫跼部應力分佈情況,對大直徑薄壁管道的優化設計及安全校驗有很好的輔助作用.

The load conditions of large diameter and thin-walled pipes are complicated,it is necessary to check the strength and stability. In this paper,using ANSYS finite element software analyzes the strength and stability of the steam turbine discharge pipes of the waste heat utilization project in a power plant. The calculation result shows that in contrast to CAESAR II software, ANSYS finite element analysis method can more accurately reflect the partial stress distribution of the pipes,it plays assistant role for optimized design and safe checking of large diameter and thin-walled pipes.
