摘要: 为提高冲击式超声波钻的排屑效率,基于压电驱动原理提出了一种单压电叠堆驱动的回转冲击超声波钻(RPUD)。RPUD仅利用单一压电叠堆两侧的振动实现了钻具的回转冲击运动,将一侧振动转变为回转运动,另一侧振动转变为冲击运动,且回转运动和冲击运动可单独调节。为实现超声波钻回转运动和冲击运动的同步谐振,借助有限元方法,对超声波钻换能器进行模态分析和瞬态分析。基于优选的结构设计参数,研制了RPUD样机并开展了钻进实验研究。实验结果验证了RPUD的钻进功能,并利用响应面方法分析了钻压力等各钻进参数对钻进效率的影响。

Abstract: To improve the chip removal efficiency of percussive ultrasonic drilling, a rotary-percussive ultrasonic drill (RPUD) is proposed based on piezoelectric driving principle, which is driven by single piezoelectric stack. The proposed RPUD uses the vibration on both sides of the single piezoelectric stack to realize the rotary-percussive motion of the drilling tool, and transfers one side of vibration into rotary motion and the other side into percussive motion. Rotary motion and percussive motion can be regulated independently. To realize the synchronous resonance of rotary motion and percussive motion, the modal analysis and transient analysis of ultrasonic drilling transducer are carried out by the finite element method. A prototype of rotary-percussive ultrasonic drilling machine was developed, and the drilling experiment was carried out based on the optimized structural design parameters. The experimental results verify the drilling function of the RPUD, and response surface method is used to analyze the influence of the drilling parameters such as weight on bit on the drilling efficiency.

Key words: deep space sampling, ultrasonic drill, piezoelectric transducer, finite element method, drilling experiment, response surface method
