Soil-Tool Interaction Theories as They Apply to Lunar Soil Simulant

Journal of Aerospace Engineering, 1995
With the establishment of a lunar base, excavation of the lunar soil will be a necessary and time-critical activity. It is the intent of this paper to establish the importance of certain excavation parameters and how they interrelate. With this approach, an overall efficiency of an excavating system can be determined and used as a basis for comparing ...

Experimental simulation of tensile behavior of lunar soil simulant JSC-1

Materials Science and Engineering: A, 2008
The return of humans to the Moon, which includes construction and infrastructure development remain a national priority for exploration of space. Thus, a thorough understanding of lunar soil properties for purposes of engineering design is required. In the past lunar soil (regolith) simulant JSC-1 has been widely used by investigators in feasibility ...

DEM parameter matching of high-dense lunar soil simulant

2015 IEEE International Conference on Information and Automation, 2015
Discrete element method (DEM) is getting a wider use in granular media study. It is a fundamental of lunar soil DEM study that matching the micromechanical parameters of lunar soil simulant with its macro parameters. In this paper, the matching work is carried out by simulating triaxial test applying PFC3D software, and the constitutive model is a ...

NAO-1: Lunar Highland Soil Simulant Developed in China

Journal of Aerospace Engineering, 2009
A new lunar highland soil simulant, NAO-1, has been created in National Astronomical Observatories (NAO), Chinese Academy of Sciences. This simulant was produced by gabbro, which includes large quantity of feldspar ( An >90) . The simulant’s chemical composition, mineralogy, particle-size distribution, density, angle of internal friction, and cohesion ...
