【摘要】：對稱破缺是產(chǎn)品結(jié)構(gòu)及其演化過程中的一個普遍現(xiàn)象,但目前國內(nèi)外對此尚鮮有關(guān)注。作者收集了600余個機(jī)械結(jié)構(gòu)對稱破缺實例,采用統(tǒng)一標(biāo)準(zhǔn)逐個分析了對稱破缺在實例中的存在方式和所起的作用。在此基礎(chǔ)上,借助知識挖掘手段,展開機(jī)械結(jié)構(gòu)對稱破缺概念、作用及其應(yīng)用的研究,主要研究內(nèi)容和成果體現(xiàn)在以下四個方面： 1、機(jī)械結(jié)構(gòu)對稱破缺概念和分類體系的建立。通過對結(jié)構(gòu)對稱破缺實例的分析歸納并借鑒課題組結(jié)構(gòu)對稱的研究成果,提出了機(jī)械結(jié)構(gòu)對稱破缺的定義,建立了包括結(jié)構(gòu)靜態(tài)對稱破缺、結(jié)構(gòu)動態(tài)對稱破缺和結(jié)構(gòu)選擇對稱破缺等類型的分類體系。 2、結(jié)構(gòu)對稱破缺關(guān)聯(lián)知識挖掘與分析。在構(gòu)建機(jī)械結(jié)構(gòu)對稱破缺實例庫和設(shè)計需求庫后,利用關(guān)聯(lián)知識挖掘算法對設(shè)計需求和結(jié)構(gòu)對稱破缺之間的關(guān)聯(lián)關(guān)系進(jìn)行了挖掘,并重點分析了其中支持度較高的幾類關(guān)聯(lián)知識,歸納了機(jī)械結(jié)構(gòu)對稱破缺在滿足功能需求、性能需求和約束需求等方面的作用。 3、不對稱匹配原理及其應(yīng)用方法研究。在關(guān)聯(lián)知識的啟發(fā)下,結(jié)合對大量產(chǎn)品改進(jìn)設(shè)計實例的人工分析,提出了不對稱匹配原理及其四種分類,歸納了不對稱匹配原理的應(yīng)用方法和流程,從對稱破缺的角度對產(chǎn)品的創(chuàng)新和改進(jìn)設(shè)計作了有益探索。 4、機(jī)械結(jié)構(gòu)對稱破缺知識應(yīng)用平臺(KAPMSS)的開發(fā)。在上述理論研究的基礎(chǔ)上,研制了集成實例管理、知識挖掘、知識管理、知識應(yīng)用四大模塊的機(jī)械結(jié)構(gòu)對稱破缺知識應(yīng)用平臺,將知識獲取與知識應(yīng)用有機(jī)結(jié)合在一起,并通過小型風(fēng)力發(fā)電機(jī)的改進(jìn)實例初步檢驗了平臺的實用性。
[Abstract]:The symmetry breaking is a common phenomenon in the structure and evolution of the product , but at present there is little concern at home and abroad . The author collects more than 600 cases of symmetry breaking of mechanical structures , and analyzes the existence mode and function of symmetry breaking in the instance one by one . Based on this , the research on the concept , function and application of symmetry breaking of mechanical structure is carried out by means of knowledge mining means . The main research contents and achievements are embodied in the following four aspects : 1 . The conception and classification system of symmetry breaking of mechanical structure is established . By analyzing the structural symmetry breaking examples and using the research results of the structure symmetry of the research group , this paper puts forward the definition of symmetry breaking of the mechanical structure , and establishes a classification system including the structure static symmetry breaking , the structural dynamic symmetry breaking and the structure selection symmetry breaking . 2 . Knowledge mining and analysis of structural symmetry breaking . After constructing symmetry breaking instance library and design requirement database of mechanical structure , the association relation between design requirement and structural symmetry breaking is excavated by using the association knowledge mining algorithm , and several kinds of association knowledge with higher support degree are analyzed , and the function of symmetry breaking of mechanical structure in meeting functional requirements , performance requirements and constraint needs are summarized . 3 . The principle of asymmetric matching and its application method are studied . Based on the theory of correlative knowledge , this paper puts forward the principle of asymmetric matching and four kinds of classification , sums up the application methods and flow of asymmetric matching principle , and makes a useful exploration on the innovation and improvement design of the product from the angle of symmetry breaking . 4 . Based on the research of the above theory , the application platform of symmetry breaking knowledge of the mechanical structure of the four modules of integration instance management , knowledge mining , knowledge management and knowledge application is developed , and the knowledge acquisition and knowledge application are organically combined , and the practicability of the platform is preliminarily tested through an improved example of a small wind power generator .
