基于ANSYS/LS-DYNA平台对两种垂直壁圆筒件有支撑板料渐进成形过程的成形路径(圆弧平移和圆弧逼近)下的节点流动和厚度分布进行了研究,并通过实验对厚度分布情况进行了验证。结果表明,与圆弧平移路径相比,圆弧逼近成形路径节点流向直壁部分比较多;而且最小厚度集中在圆角部分,能够获得比较理想的制件。 Based on the ANSYS / LS-DYNA platform, the flow and thickness distribution of the nodes under the forming process of two kinds of vertical wall cylindrical members with progressive sheet forming process (arc translation and arc approximation) were studied. The thickness The distribution has been verified. The results show that compared with the circular path of translation, the circular arc approaches the straight-walled part of the forming path, and the minimum thickness is concentrated in the fillet, so the ideal workpiece can be obtained.
