ACCURATE AND FAST SIMULATION OF ROLLING FORCE MODEL IN COLD STRIP ROLLING

Differential element method has been used with the consideration of roller and strip elastic deformation to educe the force model for cold rolling,which avoids complex differentical equation solution. In addition FEM is used to correct flatten radius and deformed area length calculation. The model combines accuracy of FEM and speed of analytic method. The model has smaller correction factor for dynamic simulation. The simulated and measured rolling forces are in good agreement. The model is important for cold rolling.
