A Novel Coupling Model for Shape Prediction
Usually strip shape is simulated by iterative algorithm through relaxation factor method. But because of the difficulty to select an appropriate relaxation factor, the iterative course is either rather unstable or too slow. To solve this problem, a novel coupling model is put forward by this essay, which combined rolling-piece plastic deformation model with rolls elastic deformation model through their basic equations, and strip shape can be calculated by only a linear equations, so its calculation course is quite steady, and the calculation speed can be improved remarkably. Simulation is performed used of 1420mm UCM cold tandem mill measured data, the results show the coupling models precision is same as iterative algorithm, however the coupling models calculation course is more steady than iterative algorithm, and its calculation time is reduced remarkably, which guarantees its practicability and reliability are more excellent, and shows well promotion value.
