Design and Analysis of Absorption Type Sampler on Star Soil

Abstract

Deep space detection is the result of human exploration of natural intrinsic motivation. To explore the Moon, Mars, target Asteroid soil strata information, meeting the needs of human living space is of great significance. For the mission of celestial bodies, an absorption type sampling method which uses the rotation and pound to burst rock and air flow excitation to obtain samples is put forward. It has characteristics of low reaction force, efficient rock-breaking, light body and low energy consumption. Further, it uses the principle of flywheel energy storage to achieve low energy consumption, passive vibration excitation magnetic control to achieve high efficient rock breaking, and the dense ball bearing shaft inherent function of rush and rotation to achieve structure lightweight. Through ADAMS software, dynamic simulation analysis is ascertained and sampler ground simulation experiment is consolidated according to different hard soil. The results show that the sampling method, can brake rock efficiently, achieve the microgravity sampling function, and provide an effective way for deep space detection.
