To meet requirements for high uniformity of the cathode electric field distribution in complex rotary part electroforming, a new optimization method based on ANSYS for anode design is proposed. Firstly a simple anode is used to establish the initial model, so as to analyse the cathode electric field intensity distribution. To solve the problem of abnormal electric field in a small area, an auxiliary electrode which is optimized is introduced. In the anode contour optimization process, the adjustment quantity of anode control points is associated with the field intensity of cathode nodes, and the anode profile is adjusted according to the normal direction of cathode nodes. With this method, the anode is designed for electroforming a nozzle simulating part and the results shows that the current density ratio of maximum to minimum on cathode surface decreases from 1.96 to 1.08.%为满足复杂轮廓回转体零件电铸中阴极电场分布高均匀性的要求,提出了一种基于ANSYS的阳极优化设计新方法.采用简单轮廓阳极建立初始模型,初步分析阴极电场强度分布.对阴极局部小面积内存在电场强度突变的情况,引入辅助电极并进行优化,以消除场强突变.在阳极轮廓优化过程中,将阳极控制点调整量与对应阴极节点场强关联,并按阴极节点法向对整体轮廓进行调整.利用该方法对电铸模拟件进行阳极优化设计,优化后的阴极电场强度最大值与最小值之比由1.96减小至1.08.
