Test Methods for Measuring Mechanical Parameter of Simulated Lunar Dust

Abstract:

Due to the preciousness of real lunar dust, the lunar dust simulant is usually employed to replace the real one in the large numbers of experimental investigations about its mechanical property and engineering property. Therefore, the investigation on mechanical property of lunar dust simulant is also extremely significant. This research has put forward several methods for measuring mechanical property, which are used to measure the parameters including particle size distribution, particle proportion, relative density, void ratio, cohesion, internal friction angle, etc. of lunar dust simulant. The lunar dust simulant is determined to be suitable for application in the moon exploration project experiment after comparing these parameters with relevant typical mechanical parameters of foreign lunar dust simulant.
