【摘要】：參數(shù)化設(shè)計(jì)過程是指從功能分析到創(chuàng)建參數(shù)化模型的整個(gè)過程。參數(shù)化設(shè)計(jì)方法作為一種全新的設(shè)計(jì)方法現(xiàn)在已廣泛被工業(yè)界所采用。它所具有的高效性、實(shí)用性等特點(diǎn)使其成為設(shè)計(jì)工作的發(fā)展方向。蝶閥產(chǎn)品絕大多數(shù)為定型產(chǎn)品,這些產(chǎn)品的系列化、通用化和標(biāo)準(zhǔn)化程度很高,這就為蝶閥產(chǎn)品的參數(shù)化設(shè)計(jì)提供了可靠的依據(jù)。同時(shí)隨著國外成熟三維CAD軟件在產(chǎn)品開發(fā)和設(shè)計(jì)領(lǐng)域的普及,其輸出二維工程圖模塊一直是它的軟肋。針對(duì)以上情況,本文基于SolidWorks對(duì)閥門的參數(shù)化設(shè)計(jì)及工程圖標(biāo)準(zhǔn)化處理進(jìn)行了研究,旨在提高我國的閥門自動(dòng)化設(shè)計(jì)水平,推廣現(xiàn)代CAD技術(shù)的應(yīng)用。 本文的主要內(nèi)容有：第一,以Solidworks API函數(shù)及Visual Basic高級(jí)語言為工具,以動(dòng)態(tài)鏈接庫的形式,對(duì)Solidworks進(jìn)仃二次開發(fā)。建立了兩類常用蝶閥模型庫,開發(fā)了蝶閥參數(shù)化建模程序,并在程序中集成了參數(shù)數(shù)據(jù)庫,最后把程序封裝生成*.dll動(dòng)態(tài)鏈接庫。第二,依照國標(biāo)對(duì)Solidworks工程圖標(biāo)準(zhǔn)化方法進(jìn)行了研究。詳細(xì)論述了與Solidworks輸出工程圖有關(guān)的系統(tǒng)選項(xiàng)和文件屬性設(shè)置及模型規(guī)范化處理方法。定制了各種圖號(hào)的標(biāo)準(zhǔn)圖紙格式、工程圖模板及材料明細(xì)表,在模板中應(yīng)用了文件自定義屬性鏈接功能,保證了模型信息自動(dòng)讀入時(shí)的準(zhǔn)確性和唯一性。總結(jié)了Solidworks繪制工程圖的技巧,把一些常用公差、尺寸添加為常用類型,把技術(shù)要求、標(biāo)題欄制作成塊,提高了工程圖的出圖效率。最后結(jié)合蝶閥參數(shù)化建模程序自動(dòng)生成符合國標(biāo)的工程圖。第三,為了檢驗(yàn)所設(shè)計(jì)產(chǎn)品的性能可靠性,本文利用ANSYS對(duì)蝶板標(biāo)準(zhǔn)模型進(jìn)行了有限元強(qiáng)度和剛度分析,控制蝶板的最大變形量和最大等效應(yīng)力在許用范圍內(nèi)保證了蝶閥的密封性能。此外還對(duì)三偏心蝶閥結(jié)構(gòu)進(jìn)行了一定的理論研究,分析了三偏心蝶閥的密封原理,推導(dǎo)了蝶板截面輪廓方程,為參數(shù)化設(shè)計(jì)提供了一定的理論依據(jù)。 本文針對(duì)蝶閥開發(fā)的參數(shù)化設(shè)計(jì)系統(tǒng)對(duì)提高我國閥門設(shè)計(jì)水平有一定的現(xiàn)實(shí)意義,對(duì)三偏心蝶閥在我國的研究發(fā)展也起到了一定的推進(jìn)作用。建立了工程圖所需的各種標(biāo)準(zhǔn)模板,利用SolidWorks輸出符合國標(biāo)的工程圖提高了Solidworks軟件的自動(dòng)化程度,有效的提高了企業(yè)的生產(chǎn)效率。
[Abstract]:The parameterized design process refers to the whole process from function analysis to the creation of parameterized model. Parametric design method as a new design method has been widely used in industry. Because of its high efficiency and practicability, it becomes the development direction of design work. Most butterfly valve products are stereotyped products, and the serialization, generalization and standardization of these products are very high, which provides a reliable basis for the parametric design of butterfly valve products. At the same time, with the popularity of foreign mature 3D CAD software in the field of product development and design, its output two-dimensional engineering drawing module has always been its weakness. In view of the above situation, this paper studies the parameterized design of valves and the standardization of engineering drawings based on SolidWorks, aiming at improving the level of automatic design of valves in China and popularizing the application of modern CAD technology. The main contents of this paper are as follows: first, with Solidworks API function and Visual Basic language as the tool, Solidworks is developed in the form of dynamic link library. Two kinds of commonly used butterfly valve model library are established, and the parameterized modeling program of butterfly valve is developed, and the parameter database is integrated in the program. Finally, the program is encapsulated to generate dynamic link library (DLL). Secondly, the standardization method of Solidworks engineering drawing is studied according to national standard. The system option, file attribute setting and model normalization method related to Solidworks output engineering drawing are discussed in detail. The standard drawing format of various drawing numbers, the engineering drawing template and the material list are customized, and the function of custom attribute link is applied in the template, which ensures the accuracy and uniqueness of the model information when it is read in automatically. The techniques of drawing engineering drawings by Solidworks are summarized. Some common tolerances and dimensions are added as common types, and the technical requirements and title bars are made into blocks. The efficiency of drawing drawing is improved. Finally, the parametric modeling program of butterfly valve is used to automatically generate the engineering drawing in accordance with the national standard. Thirdly, in order to verify the reliability of the designed products, the finite element strength and stiffness analysis of the butterfly plate standard model is carried out by using ANSYS. The sealing performance of butterfly valve is ensured by controlling the maximum deformation and maximum equivalent stress of the butterfly plate in the allowable range. In addition, the structure of three-eccentricity butterfly valve is studied theoretically, the sealing principle of three-eccentric butterfly valve is analyzed, and the section profile equation of butterfly plate is deduced, which provides a certain theoretical basis for parameterized design. In this paper, the parametric design system for butterfly valve development has certain practical significance to improve the level of valve design in China, and has also played a certain role in promoting the research and development of three-eccentric butterfly valve in China. All kinds of standard templates for engineering drawings are established, and the automation degree of Solidworks software is improved by using SolidWorks to output engineering drawings in accordance with national standard, and the production efficiency of enterprises is improved effectively.
