Abstract Traditional rotary ultrasonic vibration drilling rock (fz 2A) was proposed. The mechanism of ultrasonic vibration assisted drilling rock was analyzed, and the propagation of ultrasonic energy in the process of ultrasonic vibration assisted drilling rock was analyzed. Using the small diameter cemented carbide triangular bit as the drilling tool, the comparative test of ultrasonic vibration assisted drilling and traditional drilling of sandstone, marble, and basalt was carried out. The experimental results showed that there was a specific feed rate range for each type of rock, so that the weight on bit required for ultrasonic vibration assisted drilling was less than that of traditional drilling. With the increase of firmness coefficient of sandstone, marble, and basalt, the ratio of weight on bit to feed rate was increased, and the effective feed rate range of ultrasonic vibration assisted drilling was reduced. The ultrasonic vibration assisted drilling rock (fz > 2A) was one of the alternative methods for drilling rock on the asteroid surface.

旋转超声振动辅助钻岩试验研究

摘要 提出了传统的旋转超声振动钻孔岩石（fz 2A）。分析了超声波振动助钻岩石的机理，分析了超声波振动助钻岩石过程中超声波能量的传播。以小直径硬质合金三角钻头为钻具，对砂岩、大理石、玄武岩进行超声振动辅助钻孔与传统钻孔对比试验。实验结果表明，每种岩石都有特定的进给速率范围，因此超声振动辅助钻孔所需的钻压小于传统钻孔。随着砂岩、大理岩、玄武岩硬度系数的增大，钻压比增大，减小了超声振动辅助钻孔的有效进给速度范围。超声振动辅助钻探岩石（fz > 2A）是在小行星表面钻探岩石的替代方法之一。
