摘要:
钻取采样是未来火星探测采样任务中获取星表岩石样本的一种有效方式。压电驱动的超声波钻取采样技术以压电陶瓷作为作动元件,对火星表面复杂环境具有一定的适应性。基于高频冲击钻进的工作原理,超声波钻探装置容易刺入火星表面坚硬的岩石。作为一种轻质小巧、低功耗的钻探器,超声波钻探器非常适合火星表面岩石的原位探测采样任务。本文借助仿真和试验手段验证了超声波钻探器的岩石钻进能力和钻探效率。超声波钻探器的研制可为未来火星表面岩石的钻探采样任务提供技术参考。

Abstract:
Drilling is an effective way to obtain rock sample in future Mars exploration. Since the actuating elements of ultrasonic drilling devices are piezoelectric ceramics, they can adapt to complex environment on Mars. Based on high-frequency percussive drilling method, ultrasonic drills can easily penetrate into hard rocks on Mars. As a kind of light and compact drill with low power consumption, ultrasonic drills are suitable for Mars in-situ rock-sampling missions. By means of simulation and experimental methods, the rock-drilling ability and efficiency of the ultrasonic drill are verified. The development of ultrasonic drills can provide technical reference for future Mars rock-sampling missions.
