Novel Multipoint-drive Rotary Actuator for Extraterrestrial Celestial Ultrasonic Driller

Naiwen Deng,
Guangchao Han,
Shuqi Zhu
et al.

Abstract: Ultrasonic drilling has emerged as a prominent technique in extraterrestrial environments due to its advantageous features. However, its application in extraterrestrial sampling missions is constrained by challenges such as drilling, chip removal efficiency, and high and low temperature adaptability. Addressing these limitations, this study introduces a novel multi-point driven rotary helical longitudinal torsion horn. The initial phase involved a detailed analysis of the actuator’s structure and operational p… Show more
