摘　　要：建立了月球次表层取心钻具功耗模型,制备了与真实月壤物理机械参数相近的模拟月壤作为被钻对象,通过钻进取心实验对理论模型进行验证,得到取心钻具的功耗特性曲线并确定低能耗钻进规程。实验结果表明,取心钻具钻进功耗理论模型能够正确反映实验曲线的变化趋势,可依据模型对钻具的钻进功耗进行预估。以保证高取心率为前提,在阻力矩允许范围内,适当降低钻具回转转速,可使取心钻具的钻进功耗降低。Soil sample with physical and mechanical properties similar to real lunar soil is prepared as the drilling object.The power consumption model of coring driller is proposed and verified by coring experiments.The lower power consumption drilling procedure is obtained by analyzing the power consumption curve.To ensure high cording rate,lower rotary speed can decrease the drilling power consumption in the allowable range of resistance moment of drilling.The data calculated from the proposed model is in good agreement with the drilling experiment results.Thus,the proposed model can be used to predict the drilling power consumption.
