| 摘 要： | 美国和前苏联已完成的月球取样方法分别是载人登月取样和地面遥控取样钻机取样。基于美国和前苏联的方法,提出了一种可供我国嫦娥工程选用的月壤钻探取样方案,即用遥控取样钻机,配备硬质合金钻头、空心螺旋钻具,采用振动-回转钻进工艺。在高真空和低重力条件下,可选用空心螺旋钻具来解决排屑和钻压问题。顺利排屑的基本条件为钻具的螺旋升角应小于月壤与钻具之间的摩擦角、钻具的回转速度应大于临界转速。通过分析计算可知在月球上采用外螺旋钻具时,临界转速比在地球上要小得多,因此在获得同样的回转力矩条件下可匹配较小功率的电动机。 |
| 关 键 词： | 探月工程 遥控钻机 空心外螺旋钻具 临界转速 |
