A Study of the Structural Design of a Bottle with Vacuum Insulation

In this paper the indicators that are necessary for the optimal design of stainless steel vacuum insulation bottles are considerd. For the strength of the bottle, the critical strength of the outer cylinder depends on the shape parameters (the ratios between the height and diameter, and the diameter and thickness of the bottle). It was found that the relationship between the critical strength and the shape parameters is useful for the design of the outer cylinder. We prove this result by conducting experiments with three kinds of bottles.
