Network Parallel BEM for Band Precision Rolling

摘要

In this paper, through the network parallel computation, it is given of the three-dimensional deformation, stress field and surface force field and the distributions of surface force of the strip steel, under nine groups of rolling condition with the ratio of the width and thickness being 200, for the three-dimensional elasticity and elasto-plasticity frictional contact Boundary Element Method and the model for frictional rolling contact of strip steel precision rolling. The rolling pressure, rolling direction and the landscape orientation friction are the true surface of the strip steel and roller's interface, which isn't the equivalent surface force given by FEM and not the assumed friction given by elementary difference method. It cost five days by the network parallel computing for the rolling with the ratio of the width and thickness is 200, which is shorten 6 times than 30 days by sequential computation.
