摘　　要：基于超声波纵振原理提出一种可搭载在漫游车或机械臂末端的岩石钻进取心器。该装置利用高频纵向振动达到破碎岩石的目的,无需驱动钻具作回转运动。研究结果表明:所研制超声波钻进取心器具有较高的岩石钻进效率且断心取心可靠。Based on ultrasonic longitudinal vibration theory, a kind of rock coring tool was proposed. This tool can be easily mounted on planetary rover or end effector of robotic arm. The coring tool can break rocks using high-frequency vibration, even when no rotary motion was provided. The results indicate that the tool has relative high drilling efficiency and high reliability of breaking and coring rocks.
