Other Abstract

Aiming at the research of stellar surface access technology, a three- valves and retractable sampler, which integrates drilling and sampling functions, is designed based on the mechanism of wood wasp drilling holes. The sampler consists of three parts, which are retractable cabin, flexible arm and drill bit respectively. The retractable cabin is mainly composed of tensioning device, gear winch device and flexible roller device. The flexible arm is composed of two back-assembled tape springs, which improves its flexural stiffness and torsional stiffness, and can be folded in the retractable cabin without bulging problems. The drill bit contains the dorsal valve, the ventral valve and the middle valve, which is driven by the cam mechanism to realize the drilling, and the middle valve is used for positioning and sampling. By analyzing the parameters and the first-order critical moment of the flexible arm, the first-order critical moment estimation formula is given, which has a certain theoretical significance for the design of the sampler.
