【摘要】:概念設(shè)計的本質(zhì)是將設(shè)計問題定義為期望的功能,并求解能實現(xiàn)該功能的物理方案。該階段的工作具有最大的創(chuàng)新空間,同時也具有巨大的不確定性與模糊性,F(xiàn)有的概念設(shè)計理論與方法雖然給設(shè)計者提供了一些大體上的方向性指導(dǎo),但整個概念設(shè)計還蒙著神秘的面紗。因為,無論運用哪種現(xiàn)有方法進(jìn)行概念設(shè)計,概念設(shè)計仍然很大程度地依賴于設(shè)計者的經(jīng)驗和靈感。 本文對功能的內(nèi)涵進(jìn)行了深入的研究,對PahlBeitz提出的功能定義進(jìn)行改進(jìn),提出了一種更精煉、更嚴(yán)格的功能定義(RRDOF,A Refined and Rigorous Definition ofFunction)。以RRDOF為基礎(chǔ),沿著概念設(shè)計的基本過程,繼而系統(tǒng)地提出了一套全新的機電系統(tǒng)概念設(shè)計方法。該方法能讓設(shè)計者始終目標(biāo)明確地運用物理知識開展設(shè)計工作。全文工作摘要如下: (1)研究了功能的定義。綜合系統(tǒng)論和工程上的觀點,全面而深入地探究了功能的涵義;以PahlBeitz的功能定義為基礎(chǔ),提出了形式上更精煉、意義上更嚴(yán)格的功能定義RRDOF;詳細(xì)闡述了RRDOF的特點并分析了它與PahlBeitz功能定義的不同之處,進(jìn)一步提出了“圖式+流的結(jié)構(gòu)化描述”的功能描述方法。 (2)研究了功能推理方法。在RRDOF的基礎(chǔ)上,,提出了3條功能推理優(yōu)先規(guī)則;根據(jù)規(guī)則1,提出了一個功能推理立方體模型并給出了立方體模型的定義及建造過程;根據(jù)規(guī)則2和規(guī)則3,研究了以單類流為主線的功能分解策略,歸納了立方體模型的主要特點并討論了其適用范圍。 (3)研究了方案求解方法。闡述了方案的組成要素和描述方法;研究了基于實例重用的方案求解方法,其中著重研究了實例庫結(jié)構(gòu)化設(shè)計和功能匹配策略;研究了基于物理原理的方案求解方法,提出了基于量綱分析進(jìn)行物理原理搜索的設(shè)想。 (4)研究了方案綜合及評價策略。闡述了RRDOF對方案綜合的改進(jìn),指出了方案綜合的本質(zhì)是添加非功能構(gòu)件;探究了反映客戶共同需求的技術(shù)系統(tǒng)的一般評價指標(biāo);研究了基于匹配規(guī)則的方案綜合方法和基于匹配函數(shù)的方案綜合性能評價方法。 (5)進(jìn)行了實例研究。分別將PahlBeitz提出的系統(tǒng)化方法和本文提出的概念設(shè)計方法應(yīng)用于集成化瀝青路面修補機器的設(shè)計,驗證了本文所提出概念設(shè)計方法的可行性,展現(xiàn)了本文所提出概念設(shè)計方法的先進(jìn)性。
[Abstract]:The essence of conceptual design is to define the design problem as the desired function and to solve the physical solution that can achieve the function. At the same time, it has great uncertainty and fuzziness. Although the existing conceptual design theories and methods provide some general direction guidance to designers, the whole conceptual design is still covered with a mysterious veil. No matter which existing method is used for conceptual design, conceptual design still relies heavily on the designer's experience and inspiration. In this paper, the connotation of function is deeply studied, the definition of function proposed by PahlBeitz is improved, and a more refined and more strict definition of function is proposed. Based on RRDOF, the basic process of conceptual design is followed. Then, a new conceptual design method of electromechanical system is proposed systematically. This method enables the designer to use physics knowledge to carry out the design work. The work of this paper is summarized as follows:. (1) studying the definition of function, synthesizing the views of system theory and engineering, comprehensively and deeply exploring the meaning of function, and proposing, based on the definition of function of PahlBeitz, that the form is more refined, In this paper, the features of RRDOF are described in detail, the differences between RRDOF and PahlBeitz are analyzed, and the function description method of "structured description of schematic flow" is put forward. On the basis of RRDOF, three functional reasoning priority rules are proposed, and according to rule 1, a functional reasoning cube model is proposed, and the definition and construction process of the cube model are given. According to rule 2 and rule 3, the function decomposition strategy based on single class flow is studied, and the main features of cube model are summarized and its application range is discussed. (3) the solution method is studied, the component elements and description method of the scheme are expounded, the scheme solving method based on case reuse is studied, and the structural design and function matching strategy of case base are emphatically studied. The solution method based on physics principle is studied, and the idea of physical principle search based on dimensional analysis is put forward. (4) this paper studies the strategy of scheme synthesis and evaluation, expounds the improvement of scheme synthesis by RRDOF, points out that the essence of scheme synthesis is to add non-functional components, and probes into the general evaluation index of technical system reflecting the common needs of customers. The scheme synthesis method based on matching rule and the scheme comprehensive performance evaluation method based on matching function are studied. The systematic method proposed by PahlBeitz and the conceptual design method proposed in this paper are applied to the design of the integrated asphalt pavement repair machine, and the feasibility of the conceptual design method proposed in this paper is verified. It shows the advanced nature of the conceptual design method proposed in this paper.
