- A113 Frictional shear test of granular media at pseudo low-gravity field using magnetic device and its DEM analysis
抄録
The rational treatment of frictional interaction between lunar soil and mechanical system is one of technical issues in lunar operations. This reason is that the evaluation method for frictional interaction in lunar surface environment, for example, heavily over-consolidated soil, soft grand, low gravity and high vacuum condition. In this study, first, we performed the rotational shear test of granular media using test apparatus. Then, we combined a magnetic field device with the test apparatus in order to investigate the effect of gravity on frictional interaction. By using the test apparatus, we can perform the test under a pseudo low gravity condition in which the gravity is adjusted at 1.0 and 0.75G As a result, the effect of gravity on frictional interaction when gravitational field is 0.75G was hardly confirmed. This conclusion is also confirmed by analyzing using discrete element method.
