根据电解加工的成形理论设计辅助阴极工具的形状,应用有限元法求解拉普拉斯方程的反边界问题,设计出阴极的形状曲线。通过阳极边界电场强度的分析与对比,进一步验证所设计的阴极形状,评价阴极的设计精度。应用Matlab编程求解辅助阴极工具的外形曲线,并用ANSYS软件分析和验证电场的分布。研究结果表明,该阴极设计方法可行,设计计算误差较小,可以快速准确地设计出复杂的阴极形状。

The cathode shape was designed based on the electrolytic machining theory. The finite element method was applied to solve the inverse boundary problem of Laplace's equation, and the shape curve was designed. Through the analysis and contrast of the electric - field intensity on the anode boundary, the cathode shape designed is tested further and its accuracy is evaluated. Matlab is applied to solve the shape curve of the aided cathode and the software of ANSYS is applied to analyze and test the distribute of electric - field intensity. The research results show that the design method is feasible, the error of designing calculation is smaller, and the complicated cathode shapes can be designed quickly and accurate- ly.
