【摘要】：为降低月球开发成本,需要设计合理的开挖设备与方案,对TJ-1模拟月壤进行了不同开挖深度和推板宽度的室内开挖实验,研究各项开挖参数对开挖阻力的复合影响,为未来的真实月壤开挖提供参考。结果表明:开挖阻力随着推板的前进迅速增大,而后趋于稳定直到开挖活动停止。开挖阻力随深度的增加而增大,可以用二次多项式F=aH2+bH很好地拟合,拟合公式中的a和b随着推板宽度的增加呈线性增长关系。
[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.
