摘要: 根据电解加工的基本原理,探讨了基于间隙内简化电场和基于间隙内实际电场分布数学模型的叶片电解加工阴极设计方法,对比分析了这两种阴极设计方法对间隙内电场强度分布的影响,通过一纽工艺试验验证了阴极设计的精度.结果表明,基于间隙内实际电场分布的有限元阴极设计方法更符合电解加工的实际物理过程,阴极设计更加精确合理.

Abstract:

According to the basic principle of electrochemical machining , discussed in this paper are two kinds of cathode design methods , which were respectively based on the mathematical model of a simplified electric field and the mathematical model of actual electric field distribution in the machining gap. The effects of these two cathode design methöds on the distribution of electric field density in the gap were then compared and analyzed. Moreover ,a group of experiments was carried out to verify the design accuracy. The results demonstrate that the cathode de-sign method based on the actual electric field distribution in the gap accords better with the electrochemical machi-ning process and the corresponding cathode is more precise and reasonable.
