Abstract

Abstract: The vacuum chamber is an important component of vacuum equipment, and reasonable design and calculation of the vacuum chamber is the cornerstone of safe operation of vacuum equipment. This article takes the vacuum chamber of a certain space environment simulation device as an example to explore the design of the wall thickness of the vacuum chamber using the formula method in the design manual, the GB/T 150 diagram algorithm, and the GB/T 4732 formula method. It is concluded that the wall thickness designed according to the formula method in the design manual is relatively safe. By conducting finite element analysis on its strength and stability, and comparing the results of standard design with those of finite element analysis, it is found that the allowable external pressure values obtained from the GB/T 150 chart method, GB/T 4732 formula method, and ANSYS nonlinear buckling analysis are relatively close. This can provide a reference for the reliability and economic rationality of the vacuum chamber.
