摘　　要：将金属薄板等离子体弧圆弧柔性成形视为V形等离子体弧弯曲成形的复合，分析了圆弧弯曲件与V形弯曲件的几何关系。首次提出了参数y与圆弧面圆滑程度的关系，利用有限元分析软件Ansys中的二次开发语言ADPL编制了金属薄板等离子体弧圆弧柔性成形的仿真程序，并进行了实验研究。研究结果表明，当γ0．1～0．12时，所成形的圆弧面十分圆滑；仿真结果与实验结果基本一致。Flexible forming the circular arc of sheet metal using plasma arc can be formed by combing V-shape bending, and also the geometrical relationship between circular arc bending part and V-shape bending part is investigated, In this paper, the authors advanced the relationship between a parameter y and the degree of circular arc smoothness firstly. A simulation program for flexible forming the circular of sheet metal using plasma arc was programmed by the ANSYS Parametric Design Language （ADPL）, and the experiments were done, The results show： When y = 0.1 -0.2, the forming circular arc is very smoothness. Good correlation between the numerical simulation the experimental results, is achiered.
