基于DYNAFORM的铝箔拉深成形数值模拟研究

摘要

Aluminum foil is prone to pinholes and cracks after stamping, and it would seriously affect the barrier properties of packaging materials. To solve this problem, reasonable process parameters were proposed for deep drawing foil through numerical simulation, and the rationality was verified by experimens. An effective method to determine the foil stamping process parameters of particular packaging shape is provided.%铝箔材料冲压成形后容易出现针孔和裂纹，这会严重影响包材的阻隔性。针对这一问题，在Dyanfrom软件环境下，通过数值模拟分析得到铝箔拉深成形的合理工艺参数，并通过实验验证了参数的合理性。本文为特定包装形状下铝箔冲压工艺参数的确定，提供了一种有效的方法。
