摘　　要：钛合金因密度小、强度高以及优良的耐腐蚀性被广泛应用于航空航天、化工、船舶等重要领域。本文通过对钛合金进行传统钻削和超声振动钻削两种方式的比较研究,重点对比了两种方法中刀具的运动特性,借助ABAQUS软件对不同主轴转速和进给速度下刀具轴向力分布进行仿真分析,试验结果表明:传统钻削和超声振动钻削刀具的轴向力均随着主轴转速的增大而减小,随刀具进给速度的增大而增大;但超声振动钻削相比传统钻削轴向力降低21%,孔壁毛刺现象得到较好改善。Titanium alloys are widely used in important fields such as aerospace,chemical industry and shipbuilding due to the low density,high strength and excellent corrosion resistance.In this paper,the traditional drilling and ultrasonic vibration drilling for titanium alloys are compared.The movement characteristics of the tools in the two methods are compared.By ABAQUS software,the axial force distributions of the tools at different spindle speeds and feed speeds are compared and analyzed.Simulation analysis and experimental results show that the axial force of traditional drilling and ultrasonic vibration drilling tools decreases with the increasing spindle speed and increases with the increasing tool feed speed in both methods.The axial force of ultrasonic vibration drilling decreases by about 21%campared with traditional drilling and the hole wall burr phenomenon is better improved.
