以圆锥台为例,运用ABAQUS/Explicit建立弹塑性有限元模型,研究了半顶角(α)、工具头直径(D)和下压量(ΔZ)对零件壁厚和成形质量的影响。结果表明,半顶角对制件厚度变化起主导作用,其值越小,厚度减薄越严重;大工具头直径和小下压量有利于获得厚度分布均匀的制件。 Taking the truncated cone as an example, an elasto-plastic finite element model was established by ABAQUS / Explicit to study the influence of the half apex angle (α), tool head diameter (D) and downforce (ΔZ) on the part wall thickness and forming quality. The results show that the semi-apex angle plays a leading role in the variation of workpiece thickness. The smaller the value is, the more severe the thickness reduction is. The larger tool head diameter and smaller pressing amount are beneficial to obtain the workpiece with uniform thickness distribution.
