【摘要】：超高壓容器筒體是等靜壓設(shè)備的核心部件，其結(jié)構(gòu)形式、關(guān)鍵尺寸，對等靜壓設(shè)備使用的安全性、可靠性具有極其重要的作用。近年來隨著等靜壓設(shè)備在金屬、非金屬材料成形工藝中應(yīng)用越來越多，在食品行業(yè)、化工行業(yè)應(yīng)用也愈加廣泛，超高壓容器使用量日趨增多，預(yù)應(yīng)力纏繞式超高壓容器筒體，由于其本身所具有的安全性、可靠性、防爆性的特點，已成為等靜壓設(shè)備的超高壓容器研究重點。隨著技術(shù)的進步、預(yù)應(yīng)力纏繞理論的日益成熟，，預(yù)應(yīng)力纏繞式超高壓容器以其獨有的優(yōu)勢將擁有越來越廣闊的應(yīng)用前景。 本文以250MPa等靜壓成型超高壓容器筒體作為研究對象，根據(jù)預(yù)應(yīng)力纏繞理論，設(shè)計250MPa等靜壓成型超高壓容器筒體尺寸、結(jié)構(gòu)，繪制出筒體中的應(yīng)力分布曲線，為筒體的設(shè)計提供參考依據(jù)。 本文采用有限元數(shù)值分析方法，對工作載荷條件下的預(yù)應(yīng)力纏繞式等靜壓成型超高壓容器筒體進行了強度分析，驗證了其結(jié)構(gòu)、尺寸設(shè)計的正確性。 本文對纏繞式預(yù)應(yīng)力筒體的等剪應(yīng)力纏繞技術(shù)、工藝進行了分析、研究，提出纏繞過程中的等剪應(yīng)力控制方式與控制手段，為等剪應(yīng)力纏繞工藝與纏繞裝備的進一步研究奠定了基礎(chǔ)。
[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.
