摘要

研究薄壁圆管圆角模翻转过程有助于其在金属成形和能量吸收领域的应用。基于变形区曲率连续变化的几何模型和能量法建立一种新的描述薄壁圆管圆角模外翻过程的理论模型,得到成形半径、临界位移和稳态翻转力的理论公式并考虑摩擦效应的影响,其中临界位移为首次提出的用以描述翻转过程的物理量。分析结果表明:该理论模型得到的理论结果与数值结果和实验结果吻合;成形半径、临界位移和稳态翻转力理论预测与数值结果的相对误差均低于5%;摩擦系数对成形半径和临界位移的影响可忽略,对稳态翻转力的影响大。

Abstract

The investigation of the inversion process of a thin-walled circular tube over a circular die is helpful for their applications in metal forming and energy absorption fields. Based on the geometric model with continuously changing curvature in the deformation area and energy method, a new theory model was proposed to describe the inversion process. The expressions of forming radius, critical displacement and steady inversion force were obtained, and the effect of friction was considered. The critical displacement was first proposed to describe the inversion process. The analysis results show that the theoretical results obtained by the theoretical model are in good agreement with the numerical and experimental results; The relative errors between theoretical results and numerical results of forming radius, critical displacement and steady inversion force are all less than 5%; The friction coefficient has negligible effect on the forming radius and critical displacement, but has great effect on the steady inversion force。
