s → (2) functional position→ (3) The main function of ponents → (4) functional ponents. Featureoriented applications using structured catalogue of functional ponents that is more specific qualitative and quantitative description. At the same time developed a design suitable for product development and early software tools used by early Start. Most of the functions that can be used for mechanical products have been solution, and with only a few new functions solution dedicated, specialized in the mechanical design of a functional product mix, dedicated machinery for the evaluation of the design, manufacture windvery favorable. According to the connectivity features of mechanical parts will be consolidated into its four types: 1) A direct positioning ponents, and since there is a readjustment of the ponents。 根據(jù) “運動轉(zhuǎn)換 ”功能 (簡稱功能元 )將機構(gòu)進行分類,并利用代碼描述功能元和機構(gòu)類別,由此建立起 “機構(gòu)系統(tǒng)方案設(shè)計專家系統(tǒng) ”知識庫。同時研制出適合于產(chǎn)品開發(fā)早期和設(shè)計初期使用的工具軟件STRAT。下面介紹一些具有代表性的系統(tǒng)化設(shè)計方法。系統(tǒng)化設(shè)計思想于 70年代由德國學(xué)者 Pahl 和 Beitz 教授提出,他們以系統(tǒng) 理論 為基礎(chǔ),制訂了設(shè)計的一般模式,倡導(dǎo)設(shè)計工作應(yīng)具備條理性。 4.外文文獻翻譯原文由指導(dǎo)教師指定, 同一指導(dǎo)教師指導(dǎo)的學(xué)生不得選用相 同的外文原文。 格式按《華中科技大學(xué)武昌分校本科畢業(yè)設(shè)計 /論文撰寫規(guī)范》的要求撰寫。 目前 , 計算 機輔助產(chǎn)品的設(shè)計繪圖、設(shè)計計算、加工制造、生產(chǎn)規(guī)劃已得到了比較廣泛和深入的 研究 ,并初見成效,而產(chǎn)品開發(fā)初期方案的計算機輔助設(shè)計卻遠遠不能滿足設(shè)計的需要。同時采用了生命系統(tǒng)圖符抽象地表達產(chǎn)品的功能要求,形成產(chǎn)品功能系統(tǒng)結(jié)構(gòu)。 結(jié)構(gòu) 模塊化設(shè)計方法 從規(guī)劃產(chǎn)品的角度提出:定義設(shè)計任務(wù)時以功能化的產(chǎn)品結(jié)構(gòu)為基礎(chǔ),引用已有的產(chǎn)品解 (如通用零件部件等 )描述設(shè)計任務(wù),即分解任務(wù)時就考慮每個分任務(wù)是否存在對應(yīng)的產(chǎn)品解,這樣,能夠在產(chǎn)品規(guī)劃階段就消除設(shè)計任務(wù)中可能存在的矛盾,早期預(yù)測生產(chǎn)能力、費用,以及開發(fā)設(shè)計過程中計劃的可調(diào)整性,由此提高設(shè)計效率和設(shè)計的可靠性,同時也降低新產(chǎn)品的成本。 機械系統(tǒng)的方案設(shè)計主要是依據(jù)產(chǎn)品所具有的特征,以及設(shè)計領(lǐng)域?qū)<业闹R和經(jīng)驗進行推理和決策,完成機構(gòu)的型、數(shù)綜合。在利用數(shù)學(xué)系統(tǒng) 理論 的同時,考慮了系統(tǒng)工程理論、產(chǎn)品設(shè)計技術(shù)和系統(tǒng)開發(fā)方法學(xué) VDI2221,研制出適合于產(chǎn)品設(shè)計初期使用的多媒體開發(fā)系統(tǒng)軟件 MUSE1 Mechanical products of modern design methodology and the programme trends Summary: According to the current domestic and international product design, mechanical design scholars of the main features of thinking, product design methods summarized as a systematic programme, modular structure, based on product knowledge and wisdom of the four types. That the four methods of the anic link between features and its proposed product design puter programmes to achieve endeavors. Keyword: mechanical products。 4) A modular structure and modular ponents connectivity. And the use of symbols that prospective typical ponents and the interlinking ponents rules, thus achieving connectivity between the ponents of the algorithms and concepts visualization. 3. The characteristics of knowledgebased products in the design methodology Design methods based on product characteristics knowledge of the main features: a puter language to describe the identification and design of products features experts in the field of knowledge and experience, knowledge base and establish the corresponding reasoning machine to use the storage areas have knowledge of the reasoning mechanism and the establishment of the programmer to achieve puterassisted design products. Mechanical systems design of the programmer 5 is based on products of the main features, and design experts in the field of knowledge and experience on the volume and decisionmaking, plete body type, a few integrated.
