Lunar Rock Sampling and the Investigation & Analysis on the Physical and Mechanical Properties
摘要
Abstract
Existing form and main physical and mechanical properties of lunar rocks are directly related to the drillability, which are the basic premise and important basis for coring drill designing.Through a lot of investigation and analysis, it is found in samples in coring tubes that 40%~80%lunar rocks are in the form of large diameter particle and the proportion of lunar rocks in lunar samplers is up to 65%.The lunar rocks have wide particle size distribution with the tendency of par-ticle size first decreasing and then increasing along with the depth increasing.Mare basalts is loose, the main physical and mechanical properties are density 3.26 ~3.51g/cm3 , bulk density 3.04 ~3.34g/cm3 , porosity 0 ~10%, compressive strength about 200MPa and dynamic tensile strength 114~160MPa.关键词
