Computational Model Of Non-ferrous Metals Thermodynamic Database Architecture System

Nonferrous metal is indispensable and basic material in economic and national defense construction. It plays a wide role in construction industry, auto industry, domestic appliances industry, military project, which makes it an industry of high degree of association. At present, main nonferrous metal like copper, aluminum, lead and zinc, etc. it has over0.9industry correlation coefficient. There are abundant nonferrous metal resources in our country, for example, nonferrous metal like tungsten, antimony, rare earth, etc. account for over80%of the global output, which makes our country the most important suppliers. Besides, we have remarkable achievements in scientific research in nonferrous metal smelting technology, and utilization and development of new materials, some of which are in the high level all over the world.By means of the latest achievements of internet and database technology, nonferrous metal physical database collects and integrates research projects and data, makes related applicational calculation model through systematic analysis and classification, and finally forms a comprehensive service platform with inquiry, analysis, and prediction and computer stimulation of nonferrous metal basic data, on the basis of Internet share. As the fundamental and supporting subsystem, nonferrous metal thermodynamic database is the key point and difficult point in the whole system research because of its wide application, large number of data and complicated calculation model. In the thesis, basic data of thermodynamics are taken as a staring point, calculation model, algorithm and implementation procedure of data calculation, process calculation, predominance phase diagram calculation, complex system balance calculation and related models are under detailed research. Moreover, software frame model and access security control model of physical database are advanced on the basis of nonferrous metal physical database. The main content of the thesis is as follows.Based on functional requirement of nonferrous metal thermodynamic database, dynamic memory structure of thermodynamic data is designed, database is enlarged, and transferred model from hierarchical data to relational data is put forward, in order to store nonferrous metal thermodynamic database by making use of large relational database system and provide convenience to the following data inquiry and retrieval.Based on the feature of nonferrous metal physical database, an application model on the basis of SOA, multilayer and distributed architecture are put forward. Implementation of nonferrous metal physical client database on the basis of RIA is presented to solve the problems of traditional client deployment or dynamic graphics drawing. In the model, Services layer are added to implement foreign disclosure of system service, and integration and reorganization of heterogeneity platform and cross-system businesses. Clustering technology is adopted, load balancing is implemented dynamically, system function is optimized, data access layer is improved, O/R mapping is added and detailed information of sub-database is shielded so that system can be architected on various types of database and its flexibility is improved.Access security control model of nonferrous metal physical database based on Internet is researched and designed, to guarantee security and stability of database access process.Distributed model and programming implementation of concurrent computation of nonferrous metal thermodynamics calculation are researched and designed.Calculation formula of thermodynamic basic data and process of enthalpy, entropy and Gibbs free energy are deduced and simplified on the basis of thermodynamic theory, to make implementation by means of calculation and program with computer.Calculation model and algorithms of predominance phase diagram on the basis of M-X-Y system is researched and designed through thermodynamic balance condition.Taking advantage of smart bionic algorithm good for global optimization, on the basis of Gibbs free energy theory, improved Ant Colony Optimization algorithm is researched and designed, applied to calculation of complex system of chemical balance and phase equilibrium.Through the research and design of the above, the main function of thermodynamic calculation can be implemented and nonferrous metal thermodynamic database subsystem of improved function is formed in initial shape, to provide future imitation and stimulation of metallurgical process with basic data support and calculation platform.
