摘　　要：在电火花加工中，沿电极的轴向采用微幅超声振动可明显改善微小孔的加工性能，本试验对该系统Φ２０Ｘ５５的微型换能器进行了设计和有限元分析。The application of ultrasonic vibration on electrode along axial direction may obviously improve machining performance of hole in EDM.In this paper,we design the configuration of micro piezoelectric transducer of Φ 20 * 55 and analyse it by finite element method (FEM) And then the optimized working range form 39 to 45 Kilohertz,repressive lateral vibration and favorable amplitude are obtained

关 键 词：电火花加工 超声振动 有限元分析 换能器
