In this paper,expriments are done to study the effct of cylinder blankhold surface on rectangle box part drawing,and the effect law of between cyllinder surface and forming limits,strain distribution in deformation area are proposed.

Numerical simulation of the influence on rectangular case drawing deformation based on different blank-holder surface form;

A lot of experiments of rectangular case drawing are perfomed as a part of strudies of non-rotative symmetrical drawing forming experiments.

Based on a great deal of experiments, measurements and calculations, the law of material deformation of different parts of flange on the blank holder face in drawing of rectangular case was analyzed in this paper.

The deep drawing process of magnesium alloy rectangular box on different blank shapes are simulated by using FEM software under the same forming conditions and die.

In this paper,warm drawing process of magnesium alloy rectangular box is simulated by using MSC.

In order to further understand the non-rotary symmetric formability of sheets to provide references for forming process and mould design of large and complex automobile panel,the deformation characteristics on the curve edge of flange in rectangular box were analyzed by experiments and finite element simulation.

The regularity of the weld bead displacement is deduced by analysing the stress of the square cup stamping.
