VISUAL SIMULATION OF COLD ROLL-FORMING BASED ON OBJECT ORIENTED PROGRAMMING

To simulate the process of cold roll-forming process, a new method is adopted. The theoretical foundation of this method is an elastic-plastic large deformation spline finite strip method based on object-oriented programming. Combined with the computer graphics technology, the visual simulation of cold roll-forming is completed and the system is established. By analyzing common channel steel, the process is shown and explained including theory method, model and result display. So the simulation system is already a kind of mature and effective tool to analyze the process of cold roll forming.
