中文摘要：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。
英文摘要：Taking a cone as an example, an elastic-plastic finite element model was developed using ABAQUS/Explicit, then the influence of some relevant process parameters, such as half-apex angle (α), tool diameter (D) and tool depth (ΔZ), on the sheet thickness distribution and forming quality were discussed. The results show that half-apex angle has a great effect on sheet thickness distribution, the smaller the half-apex angle is, the bigger the sheet thickness thins; and a big tool diameter and a small tool depth make the thickness distribution more uniform.
