应用有限元分析法开发新型的低压内缸

Development of New Steam Turbine LP Inner Cylinder Using Fin ite Element Analysis

介绍并阐述了汽轮机低压内缸结构设计的思路及方案.借助有限元分析的手段,对我公司业已生产并成功投运的135MW中间再热凝汽式汽轮机原低压1号、2号内缸,仅用1个低压内缸取代作技术论证,结果证明是可行的。

The philosophy and schemes for structure design of steam turbine LP inner cylinder are introduced and described. 135MW single rehe at condensing type turbine made by STC and operated successfully in power plant is designed and developed by applying one LP inner cylinder instead of No.1 & N o.2 LP inner cylinders through finite element analysis, which shows it is feasi ble.
