In order to derive an effective scaling law, all of the possible non-dimensional numbers, called pi-numbers, were examined at first based on the principle equations of the physics related to the phenomena. One strict relationship between the non-dimensional ratio and scaling law was then derived in terms of the size between a real model and a corresponding scale model. The relationship suggests that the scale models should have the size of one sixth of the real ones when studying the motion behavior of mechanical systems on the Moon. This fact has been well known in the space community. Next, the possibilities to relax the law were investigated, hence two candidate relationships were obtained. Experiments in a vacuum chamber using simulated lunar soil were carried out to validate these relaxed laws, and concluded that inertia forces and soil-cohesion forces dominate over gravity forces for the landing dynamics. Finally, the penetration depth into surface of the moon and maximum force of landing impact were estimated.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
