一种月表采样器合理铲挖深度的研究
Research on Reasonable Excavation Depth for Lunar Regolith Sampler
摘要
Abstract
Excavation depth is an important parameter of lunar regolith sampler.The reasonable excavation depth can not only reduce the safety risk of lunar regolith sampler but also ensure certain excavation efficiency.A kind method of lunar regolith sampler is designed which excavates lunar soil by the way of oblique breaking in.For the configuration and excavation way of the lunar regolith sampler,an equation of excavation resistance torque is derived through discrete element method based on Reece model.Simulated lunar soil is constructed in the laboratory environment referring to the sample data of Apollo and the physical parameters of the simulated lunar soil is measured.The excavation depth of sampler's typical output torque are emulated and tested based on the parameters of the simulated lunar soil and the equation of excavation resistance torque.The emulation results and testing results are coincident.The reasonable excavation depth is proposed based on testing results and the designed parameters of the lunar regolith sampler.The reasonable excavation depth provides reference for lunar regolith excavation of the lunar regolith sampler.关键词
