摘　　要：通过理论和数值分析,阐述了高速走丝电火花线切割机电极丝的振动情况。利用有限元软件ANSYS模拟电极丝振动,得到了理论计算与ANSYS模拟的误差值。数值分析发现电极丝张力对频率有较大的影响,调节上下导轮间电极丝的跨度可改变其频率,而工件可起到改变电极丝原有模态振型的作用。这些结论为抑制电极丝的振动提供了理论依据。By theory and numerical analysis, expounded the vibration of wire electrode of HSWEDM machine tool. Simulated the wire vibration using finite element analysis software ANSYS, which has few error. Wire electrode tension has considerable influence to frequency by numerical analysis; adjusting the wire electrode span can change its frequency and acted workpiece changed the mode of vibration, so offered the base of a theory for reducing the wire vibration.
