Research On Similarity Measure Method And Its Realization On Software For Mechanical Products

Similarity is a prevalent phenomenon which exists between things. Similarity science focus on understanding of similarities and similar systems, clarify principles of the formation and evolution of the law, analysis of the similarity measurement, research on system similar law and its application. Based on the similarity of scientific theory, the subject studies the similarity measure method for mechanical products and object-oriented similarity measurement software technology of realization. Study on the progress of the similarity measure methods at home and abroad, and its application in the field of mechanical engineering. Based on the similarity science and complex systems theory, this paper studies the principle of similarity analysis for mechanical products, the structure of similarity elements between similarity systems, and introduces the similarity measure method of machine system.The subject realizes the research and development work of the mechanical products similarity measure software that based on SQL Server 2000 as a background database and C/S structure, the software takes Visual C++ 6.0 as the development tool.It used C/S structure of the programming system in the software development process. The software realizes the data management through SQL Server 2000 database platform for technical support. It developed the similarity measure software and realized the similarity measure methods and processes in this paper by using object-oriented method. Through the demonstration of automotive pump as the similar examples of calculation, it shows that the software proved the correctness of the software development, achieved the theory of mechanical products similar measure in practice examples of applications.
