摘　　要：汽轮机调节级是汽轮机的重要部件,是关系汽轮机能否安全可靠工作的关键部件。文章对某调节级动叶片进行了强度振动特性常规计算和有限元计算,得出调节级在工作状态下的应力状态以及频率特性,并对调节级动叶片在工作状态下的动应力进行了计算和安全评估。The control stage is one of the most important components of steam turbine, and is the key factor to ensure safety and reliability of turbine. In this paper, regular calculation and the finite element calculation method are taken to evaluate the strength, frequency and dynamic stress characteristic of control stage is obtained in operation condition. Dynamic stresses are calculated and safety is evaluated for control stage blade in operation condition.
