【摘要】：門式起重機(jī)被廣泛應(yīng)用于國民經(jīng)濟(jì)建設(shè)的各個領(lǐng)域,產(chǎn)品已經(jīng)形成多個系列,隨著經(jīng)濟(jì)建設(shè)的發(fā)展,用戶對其設(shè)計要求越來越高。因此起重運(yùn)輸機(jī)械的設(shè)計方法需要不斷地更新和完善,使其更注重經(jīng)濟(jì)性、科學(xué)性、可靠性和安全性。在傳統(tǒng)的起重機(jī)設(shè)計過程中,涉及到的參數(shù)眾多,計算公式繁瑣,人工計算效率低、設(shè)計過程不直觀、設(shè)計過程中的錯誤也不容易發(fā)現(xiàn),設(shè)計中往往需要多次反復(fù)修改、重復(fù)性工作多,很顯然這樣的設(shè)計方法已不能適應(yīng)現(xiàn)代起重運(yùn)輸機(jī)械發(fā)展的需要。同時,對功能相似或結(jié)構(gòu)相近的同系列產(chǎn)品(包括一些標(biāo)準(zhǔn)件)在該系列已有產(chǎn)品設(shè)計的的基礎(chǔ)上進(jìn)行系列化相似性設(shè)計也能大大提高產(chǎn)品設(shè)計的效率,因此,新的設(shè)計方法的應(yīng)用迫在眉睫。隨著計算機(jī)技術(shù)的發(fā)展,各類設(shè)計軟件的不斷涌現(xiàn)和升級,為起重機(jī)設(shè)計水平的提高提供了軟件支持。參數(shù)化設(shè)計技術(shù)的發(fā)展也為提高起重機(jī)設(shè)計效率提供了理論和技術(shù)支持。利用計算機(jī)強(qiáng)大的運(yùn)算功能,結(jié)合各種設(shè)計手段和先進(jìn)的設(shè)計理念進(jìn)行設(shè)計是起重運(yùn)輸機(jī)械設(shè)計的發(fā)展趨勢。 為此,本文以MDG40門式起重機(jī)為例,對主梁結(jié)構(gòu)進(jìn)行參數(shù)化設(shè)計的研究。本文設(shè)計的L型電動單梁門式起重機(jī)主梁結(jié)構(gòu)參數(shù)化設(shè)計系統(tǒng)是在研究門式起重機(jī)結(jié)構(gòu)特點、設(shè)計流程、設(shè)計方法的基礎(chǔ)上,以Visual Basic6.0為開發(fā)平臺,運(yùn)用有限元分析軟件ANSYS進(jìn)行參數(shù)化建模和優(yōu)化分析,以Access為后臺數(shù)據(jù)庫,利用Visual Basic6.0語言對SolidWorks提供的API函數(shù)進(jìn)行二次開發(fā)而形成的一個系統(tǒng)。該系統(tǒng)結(jié)合設(shè)計工程師的設(shè)計經(jīng)驗以及門式起重機(jī)的設(shè)計理論,充分考慮企業(yè)的實際需求,采用面向?qū)ο蟮南到y(tǒng)設(shè)計方法以及模塊化的系統(tǒng)劃分方法。 本文首先研究了系統(tǒng)開發(fā)的幾個關(guān)鍵技術(shù),建立了常用零部件模型庫、工程圖庫和數(shù)據(jù)庫。并重點開發(fā)了L型電動單梁門式起重機(jī)主梁結(jié)構(gòu)參數(shù)化設(shè)計系統(tǒng)。 本課題開發(fā)的門式起重機(jī)主梁結(jié)構(gòu)參數(shù)化系統(tǒng),界面友好,設(shè)計直觀,模型自動生成,能迅速發(fā)現(xiàn)干涉等裝配問題,圖紙可自動更新,減輕了設(shè)計工作量。不僅可以提高設(shè)計效率和設(shè)計質(zhì)量,而且也符合了現(xiàn)代設(shè)計發(fā)展的要求。本課題研究旨在為門式起重機(jī)的研發(fā)提供一種先進(jìn)、可靠、快速的設(shè)計系統(tǒng)。
[Abstract]:Gantry cranes are widely used in various fields of national economic construction, and many series of products have been formed. With the development of economic construction, the design requirements of gantry cranes are becoming more and more high. Therefore, the design method of hoisting and transportation machinery needs to be updated and perfected constantly to make it pay more attention to economy, science, reliability and safety. In the traditional crane design process, there are many parameters involved, the calculation formula is cumbersome, the manual calculation efficiency is low, the design process is not intuitive, and the mistakes in the design process are not easy to find. It is obvious that this design method can not meet the needs of the development of modern hoisting and transportation machinery. At the same time, the serial similarity design of the same series of products (including some standard parts) with similar function or structure can greatly improve the efficiency of product design based on the existing product design of the series. The application of new design method is urgent. With the development of computer technology, various kinds of design software are emerging and upgraded, which provides software support for the improvement of crane design level. The development of parameterized design technology also provides theoretical and technical support for improving the efficiency of crane design. The development trend of crane transportation machinery design is to utilize the powerful computing function of computer, combine all kinds of design means and advanced design idea. Therefore, this paper takes the MDG40 gantry crane as an example to study the parameterized design of the main girder structure. The parameter design system of L-type electric single-beam gantry crane is developed on the basis of studying the structural characteristics, design flow and design method of gantry crane, and taking Visual Basic6.0 as the development platform. A system is formed by using the finite element analysis software ANSYS for parametric modeling and optimization analysis, taking Access as the background database and using Visual Basic6.0 language to develop the API function provided by SolidWorks. Based on the design experience of design engineers and the design theory of gantry cranes, the system fully considers the actual needs of enterprises, and adopts object-oriented system design method and modular system partition method. In this paper, several key technologies of the system development are studied, and the common parts model database, engineering drawing database and database are established. The parameter design system of L-type single-beam crane is developed. The structure parameterized system of gantry crane developed in this paper has friendly interface, visual design, automatic generation of model, quick discovery of interference and other assembly problems, automatic updating of drawings and reduction of design workload. It can not only improve design efficiency and design quality, but also meet the requirements of modern design development. The purpose of this research is to provide an advanced, reliable and fast design system for gantry crane.
