摘要
用商业有限元软件模拟了在同一套模具和成形条件下不同毛坯外形的镁合金矩形盒拉深成形过程, 依据数值模拟结果,分析了不同坯料外形对镁合金矩形盒拉深成形的影响。结果表明:使用矩形圆角坯料比其他坯料的成形性能好。
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.Depended on the results of numerical simulation ,the influences of magnesium alloy rectangular box drawing forming on different blank shapes have been analyzed and discussed.The results show that the drawing formality of round comer rectangular blank is better than that of other blank shapes.
