Abstract

Recently, in order to improve power plant thermal efficiency, steam turbine blades have been used under the severe mechanical strength condition. In particular the blade root supports large centrifugal and vibrational forces. The optimum design for the root and groove shape of turbine blades must be performed in order to improve the mechanical reliability of turbne. In this paper, an effective method for solving this type of problem using sen- sitivity analysis based on FEM with linear programming is discussed.
