We analyze the assembly model and propose a mathematics model and tree - representing model of the assembly who not only has a small data size, but also can be manipulated easily. this thesis not only gives the virtual representing concept the instance representing one, but also defines the concept of assembly constraint such as coupling, being alignment, being coaxial and being equidirectional. based on such concepts, a revised newton - raphson iterative algorithm is proposed, which can deal with the singularity and ill - condition of jacobi matrix
首先分析了裝配體的模型問題，提出了裝配體的數學模型及樹形式表示的裝配體表示模型，模型具有數據量小、操作簡單的優點：文章對所涉及的約束諸如耦合、對齊、同軸、同向的裝配體位置描述概念進行了定義，引入了裝配約柬概念，從而提高了裝配設計效率；在此基礎上，文章討論了裝配約束的求解方法，提出了newton rapson迭代法的改進演算法，使得系統能更好地處理jacobi矩陣的奇異和病態的情形。On basis of the development of modern control technology and apply of the network technology and locale bus - mastering technology ， the paper analyzes the essential element of slab caster system : casting speed ; expatiates in detail on the network structure and communication protocol of ethernet and profibus - dp ; mainly describes the forms of control system configuration ， the function and features of its software and hardware designs ; also, introduces mainly control function of control system, for example ， sequence control, tracking system and operation and monitor function etc. and analyzed and settled the problems of control system in debugging and producing
根據傳統的控制系統存在的一些不完善的問題，基於現代控制技術的發展、網路技術以及現場總線技術的應用，從多方面考慮，決定控制層採用siemens的s7 - 400plc ，現場採用遠程i / o單元，很好的解決了信號量大而又分散的問題。針對生產工藝和機械設備的控制要求，設計了齊全的操作模式和方式，分析了板坯連鑄系統的基本要素：拉矯速度（澆鑄速度） ；根據控制功能的分配及實現，主要說明了plc控制系統的組織結構形式，系統的軟硬體設計的功能和特點。
