Abstract: Obtaining primary lunar regolith with bedding information is one of the important targets in China's lunar-landing and manual sampling project. A high-frequency impact handheld sampling device suitable for astronauts is designed comparing with foreign sampling techniques. The sampling device uses particle's single-direction motion in high-frequency impact, which can keep sample's primary bedding information, reduce power consumption, and increase coring ratio. Particle's single-direction moving effect and coring ratio will be increased through anisotropic friction morphology on coring mechanism surface meanwhile. Law of coring ratio affected by impact frequency and surface morphology has been obtained via variable frequency coring experiment, which can be technical reference for the design of manual sampling device in China's lunar landing project.
