【摘要】：壓力燒結(jié)爐其核心部位一卡箍快開結(jié)構(gòu),是一種啟閉方便、適用壓力范圍廣的快開裝置,同時它也是壓力容器發(fā)生安全事故的主要因素之一。由于其結(jié)構(gòu)的多樣性和受力情況的復(fù)雜性,目前只有日本定制了高壓和超高壓快速啟閉裝置的設(shè)計標準,但大多數(shù)快開壓力容器屬于中、低壓容器,尚未形成一套成熟的齒嚙式快開容器的工程設(shè)計方法。高壓燒結(jié)爐主要是承受交變載荷的作用,該類設(shè)備是使硬質(zhì)合金進行燒結(jié),被大量應(yīng)用在熔點高的金屬粉末中,其由上下兩端平蓋法蘭、爐體中的零件、帶夾套的筒體以及卡箍快開結(jié)構(gòu)等幾個部分組成。本論文使用有限元ANSYS軟件對研究模型進行熱-力耦合分析,在分析時依據(jù)JB4732-1995對分析結(jié)果進行強度的校核。對于高壓燒結(jié)爐的主要部分一一卡箍快開蓋結(jié)構(gòu),依據(jù)國家標準HG/T20582-2011《鋼制化工容器強度計算規(guī)定》,對卡箍快開結(jié)構(gòu)進行了常規(guī)設(shè)計,在滿足強度要求之后又對卡箍快開蓋結(jié)構(gòu)進行強度分析和安全性評定,結(jié)果證實研究模型校核合格。把常規(guī)設(shè)計和ANSYS有限元計算結(jié)果進行了對比。最后,在此分析結(jié)果上,卡箍橫梁部位大部分的應(yīng)力強度值要比在設(shè)計溫度下的設(shè)計應(yīng)力強度值小很多,存在較大的余量,所以對此處進行結(jié)構(gòu)改進,減小厚度,并且校核合格,使結(jié)構(gòu)更合理、更經(jīng)濟。
[Abstract]:The quick opening structure of the core part of the pressure sintering furnace is a kind of quick opening device which is convenient to start and close and suitable for a wide range of pressure. At the same time, it is also one of the main factors of the safety accident of the pressure vessel. Due to the diversity of its structure and the complexity of its stress conditions, only Japan has customized the design standards for high-pressure and ultra-high-pressure quick-start and close devices, but most of the fast-open pressure vessels belong to medium-and low-pressure vessels. An engineering design method for a mature rodent-type fast-opening container has not yet been formed. The high-pressure sintering furnace is mainly under the action of alternating load. This kind of equipment makes cemented carbide sintering and is widely used in the metal powder with high melting point. It is made up of the flat flange at both ends of the furnace and the parts in the furnace body. The tube body with jacket and the quick opening structure of clamping hoop are composed of several parts. In this paper, the finite element ANSYS software is used to analyze the thermal-mechanical coupling of the research model, and the strength of the analysis results is checked according to JB4732-1995. For the main part of the high pressure sintering furnace, the quick opening structure of the clamping hoop is designed according to the national standard HG/T20582-2011 (strength calculation regulations for Steel Chemical vessels), and the quick opening structure of the clamping hoop is normally designed. After the strength requirement is satisfied, the strength analysis and safety evaluation of the quick-opening structure of the clamping hoop are carried out, and the results show that the research model is qualified. The results of conventional design and ANSYS finite element method are compared. Finally, on the basis of the analysis results, most of the stress intensity values of the clamped beam are much smaller than those of the design temperature, and there is a large amount of residual, so the structure is improved and the thickness is reduced. And check the qualification, make the structure more reasonable, more economical.
