冷弯成型数值模拟与孔型CAD集成系统

建立了冷弯成型有限条数值模拟与孔型CAD集成系统，以轧辊孔型CAD设计的结果作为数值模拟系统的初始参数，由数值模拟系统分析成型过程，将位移、应变和应力等分析结果反馈到孔型CAD系统，修改初始孔型设计，绘制轧辊图。以槽钢为例，进行了孔型设计、成型过程数值模拟以及轧辊设计，分析结果与实际生产相结合，轧辊图被工厂所采用。

AN INTEGRATED SYSTEM OF NUMERICAL SIMULATION AND ROLL PASS CAD FOR COLD ROLL FORMING

An integrated system of finite strip numerical simulation and roll pass CAD for cold roll forming has been established The results of pass CAD are used as initial parameters for numerical simulation to analyze forming process The analysis results,such as displacement,strain,stress,are fed back to pass CAD system to modify primary pass design,and then the roll drawings are made As an example,the pass design,the forming process numerical simulation and the roll design for channels have been adopted at some plants, because analysis is in good agreement with the practice
