This paper investigates the mechanical properties of JLU series lunar soil simulants under different load types. It compares the pressure-sinkage and shear-strength characteristics of JLU-1, JLU-2, and JLU-3 in both ground and lunar gravity environments. The study provides insights into the behavior of these simulants under varying load conditions, which is essential for lunar rover design.
These are the records this paper contributes to the simulant, returned sample, method, and property browsers.
