| 中文摘要 | The thermal deep-drawing process of extruded magnesium alloy (AZ31B) sheet was simulated by DYNAFORM FE simulation code. Deep-drawing experiments were conducted at a temperature of 300 degrees C for the blank. The variation in blank thickness was analysed. Process defects such as wrinkling and localised thinning were predicted to optimise the corresponding technical parameters in order to produce increased formability. To improve the accuracy of numerical simulation, the blank mesh in finite element model was modified. The simulation results showed that the thinning rate near punch shoulder part of the blank reached the maximum value. So strength of this zone was the weakest in that part of the whole workpiece. The deformed workpieces had apparent anisotropic distortion behaviour in the flange, resulting from different material characteristics along different directions of the extruded sheet. All the results derived from the numerical simulations showed good agreement with the corresponding experimental results. |
