摘　　要：为研究旋转超声电解复合加工小孔的成型过程,进行了旋转超声电解复合加工小孔试验,得到了不同加工时间孔的截面,并根据试验参数,进行了基于ANSYS的二维仿真加工和三维仿真加工。对小孔的入口直径、底面直径和加工深度进行了对比分析,结果表明由于三维仿真加工中采用了管电极,并考虑了电解加工中阴极超声高频振动对电解液电导率的影响,故其仿真结果更加接近试验值,间接证明了旋转超声电解复合加工小孔三维仿真加工的可靠性,展示了不同时刻的三维加工型腔,为旋转超声电解复合加工的成型过程和成型规律的研究提供了参考。In order to study the forming process of small holes by rotary combined ultrasonic and electrochemical machining,the small holes were machined by rotary combined ultrasonic and electrochemical machining,and the cross sections of holes with different processing time were obtained.According to the test parameters,two-dimensional simulation processing and three-dimensional simulation processing based on ANSYS were carried out.The entrance diameter,bottom diameter and processing depth of small holes obtained were compared and analyzed.The results show that the three-dimensional simulation processing was feasible because the tube electrode was used and the effect of high frequency cathode ultrasonic vibration on the conductivity of electrolyte was taken into account.The simulation results are closer to the experimental values.It also indirectly proves that the method of three-dimensional simulation processing of small holes by rotary combined ultrasonic and electrochemical machining is reliability,and three-dimensional cavity at different times can be showed for the process of rotary combined ultrasonic and electrochemical machining,which provides reference for the study of the forming process and law of rotary combined ultrasonic and electrochemical machining.
