Abstract: The computer simulation of the stresses and deformation on cold strip rolling processes of 900 mm HC mill is carried out by using the third power spline streamline strip element method to analyze the three-dimensional plastic deformation of strip, by using the influencing coefficient method to analyze the elastic deformation of rolls and by using the BP neural network method to recognize the rolled strip shape pattern. The simulation results indicate that the method and the model accord with facts. The method and the model are of great important to the development of the third-dimension deforma-tion theory, the shape theory and the shape control technology.
