摘要

摘要: 通过理论计算、有限元仿真和实验分别研究圆锥形件和方锥形件不同区域的应变状态，并对工具头直径对应变分布的影响以及方锥形件不同拐角半径的应变分布进行研究，结果表明圆锥形件存在平面应变、拉-拉和拉-压这3个区域；方锥形件在4个拐角处处于拉-拉区域，发生双向拉伸变形；工具头直径越大，板料发生双向拉伸的程度越明显；方锥形件拐角越大，拐角处越接近平面应变状态。

Abstract: The deformation states of cone and pyramid parts in different areas has been done, and it studied the effects of the tool diameter on the deformation states and the strain distribution in the different corner radius of the pyramid parts, all of these are carried out by theoretical calculation, finite element simulation and experiment. The results show that the cone parts have plane strain, tension-tension zone and tension-compression zone respectively; four corners of pyramid parts are under tension-tension zone which occur double-tension; the sheet has a more obvious tendency of double-tension with the increasing diameter; the bigger corner radius of the pyramid parts lead to more similar deformation state of plane strain state around the corner.
