【Abstract】 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.更多还原
