경계요소법과 유한요소법을 이용한 발전용 고압 증기터빈 케이싱의 구조해석 = Structural Anaysis of High Pressure Steam Turbine Casings for Power Plants Using the BEM and the FEM

다국어 초록 (Multilingual Abstract)

Structural analyses are preformed for the high pressure steam turbine casings of the nuclear and the fossil power plants. An axisymmetric boundary element program for analysis of the casings is developed and applied in the process of practical structural design. To show the useful-ness and accuracy of the developed program results of the analysis are compared with those of the finite element analysis under hydrostatic test pressure, To check the validity of the axisymmetric numerical analysis of the casings the stresses resulting from the hydrostatic test pressure are measured using the strain gate. The results of the numerical analyses are compared and discussed with those of the experiments.
