| Abstract: | To fully consider the infect of all the factors on plate shape,a 3-D elastic 'hollow-roll' model and the parametric generation module of FEM model is establelished,which makes it possible to simulate a multi-pass rolling process continuously.An input data generating system is also set up which involves a mesh refinement module and parameter transfer module.Through this system,the calculation results from the former pass can be directly transferred to the next pass input file as initial conditions and the re... |
