【摘要】：快速擴散制造是為應對戰(zhàn)時環(huán)境下武器快速大批量生產的而提出的一種制造模式,加工工藝擴散是快速擴散制造體系中最為核心的技術之一。在工藝擴散過程中,制造工藝、制造資源之間存在大量不確定的矛盾問題,如何提高制造工藝應對擴散企業(yè)制造能力動態(tài)變化的適應能力是其中的關鍵問題。本文就這一問題進行相關研究,給出了制造工藝層次化基元模型、層次關系分析技術、工藝擴散矛盾問題解決技術、調整工藝選擇技術,最后結合技術方法研究開發(fā)了葉片制造工藝快速擴散原型系統(tǒng)。 全文的主要研究內容如下： 1.采用基元理論,構建葉片制造工藝擴散層次化模型,設計了制造任務層、制造工藝層、制造資源層三個層次信息模型,在層次模型的基礎上設計了相鄰層次之間的連接映射關系和任務-資源相隔層間的匹配關系,給出了基于制造任務的制造資源選擇計算過程。 2.提出可拓變換制造工藝矛盾問題解決方法。分析了葉片制造工藝擴散過程中矛盾產生機理和葉片制造工藝的可擴散性,設計了葉片制造工藝擴散流程和矛盾消解流程,結合多種變換方法對葉片制造工藝擴散矛盾模型中的工藝、制造資源等做可拓變換,尋求解決工藝擴散中的矛盾問題消解機制,給出工藝擴散過程中矛盾消解策略。 3.提出基于多維關聯函數的葉片調整工藝選擇方法。分析調整工藝對擴散制造產生的影響,并引入關系矩陣和基于實例搜索的方法量化影響,得到調整工藝的影響值。在影響約束的基礎上,通過多維關聯函數計算,生成符合主制企業(yè)需求的擴散工藝調整方案。 4.結合提出的理論技術方法,設計開發(fā)了葉片制造工藝快速擴散驗證系統(tǒng),初步驗證了理論技術方法的可行性和有效性。
[Abstract]:Rapid diffusion manufacturing is a manufacturing model proposed to deal with the rapid mass production of weapons in wartime environment. The process diffusion is one of the core technologies in the rapid diffusion manufacturing system. In the process of process diffusion, there are a lot of contradictions between manufacturing process and manufacturing resources. How to improve the adaptability of manufacturing process to the dynamic change of manufacturing capability is the key problem. In this paper, the relevant research on this problem is carried out, and the hierarchical primitive model of manufacturing process, the technology of hierarchical relationship analysis, the technology of solving the problem of process diffusion contradiction, and the technology of adjusting process selection are given. Finally, a prototype system for rapid diffusion of blade manufacturing process is developed. The main contents of this paper are as follows: 1. Based on the basic element theory, a hierarchical model of blade manufacturing process diffusion is constructed, and three levels of information models are designed: manufacturing task layer, manufacturing process layer and manufacturing resource layer. Based on the hierarchical model, the connection mapping relationship between adjacent layers and the matching relationship between task and resource are designed, and the process of manufacturing resource selection based on manufacturing task is given. 2. A method to solve the contradiction problem of extension transformation manufacturing process is proposed. The mechanism of blade manufacturing process diffusion and the diffusibility of blade manufacturing process are analyzed. The blade manufacturing process diffusion process and conflict resolution process are designed. Combined with various transformation methods, the process and manufacturing resources in the process diffusion contradiction model of blade manufacturing are transformed, and the mechanism of resolving the contradiction problem in the process diffusion is sought, and the resolution strategy of the contradiction in the process diffusion process is given. 3. A method of blade adjustment process selection based on multidimensional correlation function is proposed. The influence of adjusting process on diffusion manufacturing is analyzed, and the influence value of adjustment process is obtained by introducing the relation matrix and the method of case search. On the basis of influencing constraints, the diffusion process adjustment scheme in accordance with the demand of the main enterprise is generated through the calculation of multidimensional correlation function. 4. A rapid diffusion verification system for blade manufacturing process is designed and developed in combination with the proposed theoretical and technical methods. The feasibility and effectiveness of the theoretical and technical methods are preliminarily verified.
