One of the missions is the sample collection of the asteroid. A large amount of sample collection and the collection of the subsurface material and the stratified sample collection etc. have been enumerated to the achievement item of this mission, and the sampling system that is appropriate for respectively is examined. In the stratified sample collection, the Harpoon & Penetrator method (H&P method) is examined., In the present study, the sampling system by the method is tested executed from two aspects. In the first, we study element affecting the performance of penetration. The penetration velocity is changed as a parameter in order to study, and the relation between the penetration depth and the penetration velocity, and the velocity necessary for 300mm sampling is examined, influence by the difference of the corer shape is studied by changing, the outer diameter of the corer. The relation between the penetration depth and the load is also studied in order to study the effect of the load on penetration. In addition, empirical formula and theory formula in both experiments are established, and compared. In this paper, the results are reported obtained by both of the experimental results., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065115039}, pages = {238--243}, publisher = {宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS), Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)}, title = {Study on penetration performance on constant penetration velocity using all-purpose material test machine}, volume = {20}, year = {2011} }
