Abstract：

The three-dimensional numerical simulation is applied for the roller die drawn of Y model to deformed course of drawing shaped,the metal floating law and deformed condition is given with the form of cloud atlas.The strain and the stress site in course are achieved,and the influence of deformation and coefficient of friction on drawing force is analysed.The radial load which is hard to measure is obtained through simulation in practice,and a new method to shorten the roller mould design period is offered.
