摘　　要：低压内缸是汽轮机中的重要的承压部件,通常设计为焊接结构,在设计过程中必须分析内缸本体结构上的开口对其造成的应力集中,从而采取加厚材料方式进行补强以降低局部应力水平的效果。简要介绍了不同的低压内缸开口位置及其对应的计算方法和补强方式,为短周期项目汽轮机低压内缸开口补强设计提供了简易算法。The LP inner cylinder is an important part in the steam turbine unit, normally is designed to be the welded structure. When designing, the stress concentration problem at the opening structure in the inner cylinder proper should be considered fully, and through thickening material to reinforce the cylinder structure to reducing the local stress level. This paper describes the application of the calculation method of the opening structure in the LP inner cylinder and the corresponding reinforcement method in the LP inner cylinder design , so as to offer a simple calculation method for some short cycle steam turbine LP inner cylinder design.
