| Abstract: | It introduces the existing strength calculation method of nozzle diaphragm, that is calculation principle, characteristics and detail calculation method of common method (Wahl method, M-V method) and finite element method (FEM). The No.8 nozzle diaphragm strength of one power station is calculated by above-mentioned methods. Especially in using the FEM, there exist distinguishing features at the time of determining the calculation mode including boundary setting, grid division, differential pressure and temperature load action of steam. |
