| Abstract: | The test equipment KM6 for airship is a large complex vacuum vessel with four elliptical shells, two cylindrical shells, a cone shell and three groups of flanges. This paper presents the analysis of strength, stiffness and stability of the vessel by finite element method. An improved design scheme was developed. The results are approved by the test to the vessel. |
