Abstract


Coins The quality is directly related to the image and credibility of national and Minting industry , traditional design methods often rely on the experience of designers in the production of trial and error to adjust the process , the development cycle is long , the high cost of test , product quality is not easy to be guaranteed. In recent years, with the finite element simulation techniques become more sophisticated , appeared on the market a lot of finite element simulation software , such as ANSYS , the DEFORM 3 D, ABAQUS , the software can solve various types of finite element simulation problems , very powerful . But they are not strong professional coin stamped and formed some special problems can not be solved . Therefore, the development of a professional coin embossed forming simulation software with high practical value . The subject comes from a cooperative project with the Shenyang Mint coins embossed forming simulation . \Developed a coin embossed forming finite element simulation software post-processing system COINFORM P < / sub > OST erected OpenGL - based graphics platform , true reproduction of the coin imprint forming process . Memory-mapped file technology to achieve a large data read , to solve the traditional method of reading the file slow and memory problems . Graphics display method has been improved to achieve large-scale grid (millions of unit grid) real-time display . Dimensional finite element hexahedral mesh section triangulation algorithm to achieve the the sectional split function and internal physical quantity distribution contour plot shows that the algorithm is simple, practical, fast calculation , can be used for large-scale grid cell . . Shenyang Mint actual production combined to develop a Coin minting process blanks the flow of material , mold and blanks contact state judge , the frictional force acting contour display , two physical quantity distribution and other functions to help designers analysis forecast coin minting process defects . The operating mechanism of the database system , Visual C development ODBC database and database SQL language , build a successful process analysis expert system database . Developed a professional coin stamped and formed post- processing system for finite element simulation COINFORM P OST .
