深小孔超声振动钻削轴向力的仿真与实验研究

建立深小孔轴向振动钻削加工仿真分析模型,针对轴向力通过DEFORM-3D有限元软件进行了超声振动钻削与普通钻削仿真,对两组仿真结果进行分析比较,并在超声轴向振动钻削装置上对不锈钢板进行了深小孔振动钻削和普通钻削实验,利用压电传感器测量了振动钻削和普通钻削加工的轴向力。实验结果与仿真结果对比表明:仿真结果与实验结果偏差低于8%,超声振动钻削的平均轴向力小于普通钻削的平均轴向力,钻削过程平稳。

Simulation and Experimental Study of Ultrasonic Vibration Drilling Axial Force in Deep Hole

Simulation analysis model of axial vibration drilling in vertical deep hole is established. Ultrasonic vibration drilling and ordinary drilling simulation analysis was carried out for axial force by DEFORM-3D finite element software, analysis and comparison of two sets of simulation results were carried out, and in the ultrasonic axial direction deep hole vibration drilling and ordinary drilling experiments were carried out on the stainless steel plate on the vibration drilling device. The axial force of the vibration drilling and the ordinary drilling was measured by the piezoelectric sensor. The comparison between the experimental results and the simulation results show that the deviation between simulation results and experimental results is less than 8%. The average axial force of ultrasonic vibration drilling is smaller than that of ordinary drilling, and the drilling process is stable.
