The Improved Design of Some Shrunk Super High Pressure Cylinder Based on Equal Strength Theory

Abstract:

According to the equation of shrunk interface pressure and the condition of diametrical ratio based on the theory of equal strength, it is found that the diametrical ratio isn’t true of the condition of diametrical ratio and the distribution of stress isn’t very equality through analyzing and calculating the diametrical ratio and stress to a super high pressure cylinder. Then aim at the problems existed in the super high pressure cylinder, it is taken the improved design. The super high pressure cylinder has much better than original one in distributing of stress. It is shown that the improved design project has a better technical result.
