一种月球熔岩管钻进的超声波钻探器

An Ultrasonic Drill for Lunar Lava Tube Drilling

  • 摘要: 提出一种采用多点驱动旋转的螺旋槽圆锥复合型变幅杆结构,并研制了适用于熔岩管内壁钻进的高性能超声波钻探器;为预测超声波钻探器响应特性,利用等效阻抗网络模型对超声波钻探器进行了建模与分析。通过低重力多角度模拟钻进试验与数据分析,验证了该钻探器在熔岩管复杂地况应用中的可能性。结果表明,钻杆直径为3 mm、钻压力为10 N时,钻进速度随开孔角度的增加而增加,垂直钻进时钻探器最大空载回转速度为506 rad/min,钻进速度为6.4 mm/min,钻进时回转转速为259 rad/min。

     

    Abstract: In this paper, a helical groove conical composite horn structure with multi-point drive rotation was proposed. A high-performance ultrasonic driller suitable for drilling in the inner wall of lava tubes was developed. An equivalent impedance network model was used to model and analyze the ultrasonic driller to predict the response characteristics of ultrasonic driller. The possibility of this drilling probe in applying complex ground conditions of lava tubes was verified through low gravity multi-angle simulated drilling tests and data analysis. The results show that the drilling rate increases with the increase of the hole’s opening angle for a drill rod diameter of 3 mm and a drilling pressure of 10 N. The maximum unloaded rotary speed of the driller is 506 rad/min, the drilling rate is 6.4 mm/min for vertical drilling, and the rotary speed while drilling is 259 rad/min.
