摘      要：The diaphragm of steam turbine is one of the main parts of the passage unit for air flowing and the diaphragm of steam turbine is generally made by welding, but during the course of welding, some cracks often have happened, these cracks threaten safety production on the spot, so it is necessary to analyze the strength of steam turbine diaphragm with a crack. For studying its working condition and performance with a crack, the three-dimensional finite element model （FEM） with the software ANSYS 10.0 is established according to the actual working parameters. With the model, the deformation results and stress field results are analyzed and the maximum displacement and stress value are calculated, meanwhile, the maximum stress change with crack depth of steam turbine diaphragm is analyzed. It provides a good foundation for solving the problem in production.
