3D DEM analysis of soil excavation test on lunar regolith

To validate the application of three-dimensional (3D) discrete element method (DEM) on modeling the excavation process, a discrete analogue of lunar regolith simulant is excavated under terrestrial conditions using DEM and the results were compared with the previous experimental data using TJ-1 lunar soil simulant. The soil failure mechanism is first described at different …

In situ and induced stresses - Rocscience Inc.

situ and induced stresses is an essential component of underground excavation design since, in many cases, the strength of the rock is exceeded and the resulting instability can have serious consequences on the behaviour of the excavations. This chapter deals with the question of in situ stresses and also with the stress changes

Microwaving Water from Moondust | Science Mission Directorate

The microwaves heated the simulant enough to extract water, even though the soil was as cold as it would be on the Moon." At least 95 percent of the water added to the simulant was extracted (vaporized out of the soil) with 2 minutes of microwaving. "And we were able to capture 99 percent of the vaporized water in our cold trap," says

Percussive digging systems for robotic exploration and

Mar 14, 2009 · A percussive digging system has been demonstrated to decrease the amount of downforce needed to penetrate a given soil, thus reducing the required reaction loads and robot mass. Preliminary testing of a percussive digging system in compacted lunar regolith simulant, JSC-1A, has demonstrated a 15 x (fifteen times) reduction in the downforce necessary to …
