摘要

测量火星土壤岩土特性的仪器提供了高价值的科学机会和高优先级的任务支持能力,为侦察、科学和工程服务。这种仪器可用于表征钻井、着陆、通过性和其他地面作业的地形。然而,迄今为止,火星探测任务中还没有测量岩土特性的仪器。本文研究了使用火星2020毅力号火星车的研磨钻头工具进行风化层强度测量的情况。毅力号火星车的研磨钻头与Bevameter形状相似,Bevametter是一种常用于收集工程岩土数据以评估地形可穿越性的工具。为了证明可以使用研磨钻头来表征土壤强度的方法,使用商用现成组件设计和建造了一个模拟飞行系统的便携式试验台。开发了一种数据处理管道,将原始测量值转换为土壤强度。对三种具有不同力学性能的表征模拟物进行了测试。结果表明,该研磨钻头能够在具有量化不确定性的情况下进行剪切和承载强度测量,并首次证明了使用标准科学仪器进行受控岩土分析的能力。

期刊介绍: The Journal of Terramechanics is primarily devoted to scientific articles concerned with research, design, and equipment utilization in the field of terramechanics. The Journal of Terramechanics is the leading international journal serving the multidisciplinary global off-road vehicle and soil working machinery industries, and related user community, governmental agencies and universities. The Journal of Terramechanics provides a forum for those involved in research, development, design, innovation, testing, application and utilization of off-road vehicles and soil working machinery, and their sub-systems and components. The Journal presents a cross-section of technical papers, reviews, comments and discussions, and serves as a medium for recording recent progress in the field.
