摘要
基于有限元方法分析了核电汽轮机低压末级叶片在低负荷运行的安全性,以末级叶片的静强度、动频率,以及不同负荷下的动应力为主要研究内容,给出了核电汽轮机组在调峰低负荷工况下的的运行安全性指导。
Based on the finite element method,the safety of the low-pressure last stage blade of a nuclear steam turbine at low loads is analyzed.The static strength,dynamic frequency and dynamic stress of the last stage blade at different loads are taken as the research contents.The operation guidance is provided focusing on the safety of the nuclear steam turbine under low load conditions such as the peak shaving.
