【Abstract】 A software of automatic mesh generation for analysis of shell of scroll compressor is developed by using the three-dimensional solid element to divide the mesh of the shell. Stress and deformation diagrams of the shell of the scroll compressor are derived. The critical cross-section is found and the structure strength is checked. The experiment has verified that the result of stress testing coincides with that of FEM analysis satisfactorily, so that it can be recommended as a reasonable determination method for the shell construction.更多还原
