摘要：
The ultrasonic drill has the characteristics of lightweight, low power consumption, the small axial force required, easy real-time detection and in-situ analysis, and good adaptability to different objects. It is highly anticipated in exploring new scientific drilling technologies and new methods suitable for deep space exploration. In order to improve the adaptability of the drill to different drilling objects and its design efficiency further, the influence of the structural parameters of the ultrasonic driller is studied. The frequency is mainly considered to be affected by the number of collisions, the vibration of the spring and drilling rod, and the vibration of the drilling rod itself. On this basis, a physical model of the influencing factors was established. Experiments are used to examine how the spring stiffness, initial preload, and mass of the free masses affect the output frequency, displacement, and speed. The effect that the initial preloads of the spring have on the frequency is more significant, followed by spring stiffness and mass of the free masses. Finally, a technical reference for the optimization design of variable frequency ultrasonic drills suitable for high-efficiency drilling of objects with different hardness is provided. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
