英文摘要To enhance the precision of the discrete element model for lunar soil-tool simulation work, this paper introduces a novel discrete element model of lunar soil incorporating particle shape and the van der Waals forces between particles. The effect of mesoscopic parameters on peak stress and failure point are systematically calibrated in the model by triaxial compression stress-strain curves. The results show that six meso-parameters have significant impact on the mechanical response of the model, including effective modulus, rolling friction coefficient, normalto-shear stiffness ratio, damping coefficient, maximum attractive force and attraction range. The model accurately simulates complex mechanical behavior in both loose, dense lunar soils and soil-tool interaction. This study lays a foundation for future lunar soil-anchor interaction simulation and the interpretation of lunar soil mechanical parameters.
