[Abstract]:Ultra-high pressure vessel cylinder is the core component of isostatic pressure equipment. Its structure, key dimensions, safety and reliability of isostatic pressure equipment are very important. In recent years, with the application of isostatic pressure equipment in forming process of metal and non-metallic materials, and in food industry, chemical industry is more and more widely used, the usage of ultra-high pressure vessels is increasing day by day, and the prestressing wound type ultra-high pressure vessel tube is also used. Because of its characteristics of safety, reliability and explosion-proof, it has become the focus of research on EHV vessels of isostatic pressure equipment. With the development of technology and the maturity of prestress winding theory, the prestressing winding ultra-high pressure vessel will have more and more broad application prospects with its unique advantages. In this paper, the 250MPa isostatic pressure forming ultra-high pressure vessel cylinder is taken as the research object. According to the theory of prestress winding, the size and structure of 250MPa isostatic pressure forming ultra-high pressure vessel cylinder are designed, and the stress distribution curve in the tube body is drawn out. It provides reference for the design of the cylinder. In this paper, the finite element numerical analysis method is used to analyze the strength of the pre-stressed winding type EHV vessel cylinder under the working load, and the correctness of the structure and dimension design is verified. In this paper, the technology and technology of the twining prestressed cylinder with equal shear stress are analyzed and studied, and the control mode and means of the equal shear stress in the winding process are put forward. It lays a foundation for further research on the process and equipment of iso-shear stress winding.
