The door is the access for the test piece and personnel, and it is one of the important parts of the vacuum chamber. This paper introduces a kind of door of a large vacuum chamber, which moves radially along the ground guide rail. Because of the risk of overturning, we use the finite element software to create a finite element model, define the material properties, and apply the load. On this basis, we carry out stress analysis, displacement analysis and overturning analysis. According to the analysis results, we give two optimization methods for anti-overturning. Finally, we analyse the overturning resistance of the optimized model.
