论文摘要
减少建造诸如登陆垫和爆炸墙之类的项目所需的力量可能是降低建立月球定居点成本的主要驱动力之一。互锁驱动系统通过将铰接式尖峰穿透地面并利用地面的自然强度进行牵引来产生牵引力。尖峰会产生高度的重量比，并在柔软，岩石和陡峭的地形，节能操作中有良好的移动性，其设计相对简单。通过定期穿透地面，尖峰还可以实现对各种地面特性的原位测量，包括穿透性抗性，温度和pH。在这里，我们提出了一个带有互锁尖峰的轻度月球推土机的概念，该尖峰使用刀片和开膛手在短距离上放松和移动土壤，从而在原位绘制地面特性，并使用此信息来构建着陆垫和爆炸墙，并以其他目标和高效的方式与地面相互作用。关于地中海土壤的试验表明，这个概念有望满足月球挖掘机的许多基本要求。为了更好地预测月球或火星环境中的性能，需要对相关土壤模拟物进行实验。
Reducing the forces necessary to construct projects like landing pads and blast walls is possibly one of the major drivers in reducing the costs of establishing lunar settlements. The interlock drive system generates traction by penetrating articulated spikes into the ground and by using the natural strength of the ground for traction. The spikes develop a high pull to weight ratio and promise good mobility in soft, rocky and steep terrain, energy-efficient operation, and their design is relatively simple. By penetrating the ground at regular intervals, the spikes also enable the in-situ measurement of a variety of ground properties, including penetration resistance, temperature, and pH. Here we present a concept for a light lunar bulldozer with interlocking spikes that uses a blade and a ripper to loosen and move soil over short distances, that maps ground properties in situ and that uses this information to construct landing pads and blast walls, and to otherwise interact with the ground in a targeted and efficient manner. Trials on Mediterranean soil have shown that this concept promises to satisfy many of the basic requirements expected of a lunar excavator. To better predict performance in a lunar or Martian environment, experiments on relevant soil simulants are needed.
