Abstract

Numerical simulation has significant advantage in analyzing the interaction between rigid wheel and lunar soil simulants and designing the lunar vehicle wheel under complex circumstances. The computer aided design software CATIA and 3D Discrete Element Method simulation software PFC3D were combined by the interface codes and the embedded FISH language in PFC3D. Then, this method was used to establish the dynamic simulation system of interactions between the wheel with lugs and loose lunar soil stimulants. The dynamic simulation system was validated by the wheel soil-bin test and then was utilized to simulate that the wheel with bionic lug and the wheel with rectangle lug travel on lunar soil simulants with different slip rate. The result indicated that wheel with bionic lug had larger traction and well stability than wheel with rectangle lug.
