电解加工钛合金异型腔薄壁流场仿真分析及实验研究

摘要

The tool electrode is improved to solve the problem about the drum structure in the side of titanium alloy cavity during the process of electrochemical machining. By using Comsol Multiphysics 5.0,we have done some simulation analysis of flow field,according to the simulation result we improved the electrode structure and do some experiments. The simulation result and experiments shows that the new electrode can constraint the flow field during the process of electrochemical machining and let the the distribution of fluid speed uniformity ,improved the machining precision.%针对电解加工钛合金型腔过程中出现的两侧薄壁易形成鼓形的加工现象,对工具阴极结构进行了改进.用Comsol Multiphysics 5.0对其流场进行了仿真分析,根据仿真结果确定了改进后的阴极结构,并进行了工艺实验.仿真与实验结果表明:改进后的阴极能对加工过程中的流场进行约束,达到加工表面流体速度分布均匀及提高加工精度的要求.
