[Abstract]:In order to reduce the development cost of the moon, it is necessary to design reasonable excavation equipment and scheme. The indoor excavation experiments with different excavation depth and push plate width are carried out to simulate the lunar soil by TJ-1, and the compound influence of various excavation parameters on the excavation resistance is studied. It provides a reference for future lunar soil excavation. The results show that the excavation resistance increases rapidly with the advance of the thrust plate, and then tends to stabilize until the excavation activity stops. The excavation resistance increases with the increase of depth, which can be fitted well by quadratic polynomial F=aH2 bH. A and b in the fitting formula increase linearly with the increase of the thrust plate width.
