双体振贯采样磁力驱动式月壤采样器设计

Design of Double-Body Vibration Penetration Lunar Soil Sampler by Magnetic Driven

  • 摘要: 为降低月壤采样器的功耗,并减小工作反力,提出一种双体振贯式采样方法,详细设计了两种不同磁力驱动方式的采样器,采用电磁仿真软件得到了采样器的驱动力,利用离散单元法数值模拟软件研究了颗粒单向运移特性,开展了采样器对模拟松散月壤和月壤硬岩的掘进采样试验,验证了采样器的驱动力大小。试验结果表明:采样器针对模拟松散月壤具有较高的掘进速率,对模拟月壤硬岩具有一定的破碎掘进能力。可为未来深空探测星壤采样装置设计提供参考。

     

    Abstract: A double-body vibration penetration sampling method is proposed, the working principle of the double-body vibration penetration is analyzed and designs two sampler with different magnetic driving modes, and carries out detailed structural design for key parts of the sampler, and obtains the driving force of the sampler through electromagnetic simulation software. Particle unidirectional transport characteristics were investigated using the numerical simulation software of the Discrete Element Method. The driving force of the sampler is verified by experiments and the excavation sampling test of the sampler to simulate loose lunar soil and hard rock of lunar soil is carried out. The results show that the sampler has high excavation rate for simulated loose lunar soil and has decent breaking and excavation ability for simulated hard rock of lunar soil.
