摘要： 单因素试验表明在相同加工条件下旋转超声电解复合加工小孔效率优于旋转电解加工小孔,为研究阴极旋转和高频振动对旋转超声电解复合加工流场的影响,基于有限元ANSYS CFX软件建立了旋转超声电解复合加工流场仿真模型,分析了阴极旋转和阴极高频振动下加工间隙内的流场变化。分析结果表明:阴极旋转使得电解液绕流,对电解液速度、压力影响较小,而阴极高频振动使得加工区发生抽吸,加速了电解液的流动,使得加工区内电解液压力波动变化,有利于电解液的更新与电解产物的排出。

Abstract: The results of the single-factor experiments shows that the efficiency of small holes machined by the rotary combined ultrasonic and electrochemical machining is better than that by the rotary electrochemical machining at the same machining conditions.In order to analyze the effect of the rotation and the vibration of the cathode to the fluent field of the Rotary Combined Ultrasonic and Electrochemical Machining (RCUECM),the fluent simulation model of the RCUECM was established based on the ANSYS CFX.The results showed that the around flow is produced at the machining areas by the rotation of the cathode,which have little effect on the velocity and pressure of the electrolyte and the suction effect is produce by the vibration of the cathode,which accelerates the flow of the electrolyte and makes the pressure of the electrolyte fluctuate in the processing area,these are helpful for the updating of the electrolyte and the charging of the produces.

Key words: Rotarycombined Electrochemical Machining (RCUECM), small holes, fluent field, geometric model, electrolyte
