TJ-1模拟月壤的研制
Development of TJ-1 lunar soil simulant
摘要
Abstract
Tongji-1 lunar soil simulant (TJ-1 for short), which is originated from red volcanic ashes from Jingyu County, Jilin Province, was recently invented by drying, crushing, sieving and adjusting the gradation.Physical and mechanical properties of TJ-1 lunar soil simulant (e.g., mineralogy composition, shape of particles, density, specific gravity, internal friction angle, cohesion, compression index, dynamic shear modulus, damping ratio and moisture absorption properties) are measured.TJ-1 demonstrates certain similarity to lunar regolith in terms of physical and mechanical properties, and it is an ideal substitute of lunar regolith located from 0 to 30 cm below the lunar surface in the mare region on the moon.Compared with other simulants introduced in the literatures, TJ-1 has an internal friction angle as high as 45° and hence is advantageous over other simulants when high shear strength is desired.关键词
