摘要：

月壤与采样机具间的相互作用在月球自主采样器的设计、性能评价、控制和仿真等方面具有重要作用，目前对于月壤与采样机具间相互作用中的钻进负载研究尚不充分。本文基于被动土压力理论，根据不同的土体切削状态，将切削刃前土体分为堆积区和破坏区，重点分析堆积区土体和破坏区土体对总钻头负载的贡献，建立了月壤取心钻头钻进松散土体的钻进负载模型。HIT 2型取心钻头和HIT\|LS1#模拟月壤的钻进试验结果表明，钻进负载理论模型与实际情况具有较高的吻合度。

Abstract:

The interaction between drill tools and lunar soil played an important role in the field of structure design, performance evaluation, dynamic control,and simulation of lunar autonomous sampler. However, research on the interaction between drill tools and lunar soil is not sufficient to reveal the source of drilling load. Based on the theory of passive earth pressure, it is proposed that the soil mass on the rake face of cutting blade is divided into deposition zone and failure zone according to different soil mass cutting states. Based on the analysis of the contribution from soil mass of deposition zone and failure zone to the total drilling load. a drilling load model for penetrating loosened lunar soil simulant is established. In the end, the drilling load model is verified based on the experimental results of HIT LS1# lunar soil simulant and HIT 2 drill bit.
