パラレルワイヤ駆動機構を用いた人体の転倒実験装置 : 座位での転倒評価の検討 Experimental apparatus for fall behavior of human by using parallel wire mechanism (consideration of evaluating fall at sitting posture) Tachiya, Hiroshi Arai, Yuki Okuno, Kosuke Miyazaki, Yusuke Nishimura, Seiji 10216989 立矢, 宏 荒井, 優樹 奥野, 公輔 70432135 宮崎, 祐介 70251965 西村, 誠次 This study describes an equipment to evaluate potential of fall of human in seated position. The equipment can make a subject fall safely by supporting the upper body with a wire parallel mechanism. Therefore, the equipment can measure behavior of a subject at fall moment and obtain evaluation data of fall behavior. The wire parallel mechanism consists of four wires connecting the base chair to the output link and can generate spatial 3DOF motion. The output link is attached to the thorax of a subject so as to support and control 3DOF motion of the upper body. Each wire has strain-gages to detect its tension. Furthermore, a force-plate is set on base chair to measure the center of pressure (COP) for comparison. The equipment uses measured wiretension, posture of the wire parallel mechanism and COP as evaluation of fall. The wire-tensions change sharply at fall moment and the posture of the mechanism show the tendencies of potential of fall of a subject clearly. Further human body can be supported by the wire parallel mechanism after falling. Thus, it has been confirmed that the proposed equipment can measure potential of fall of human safely. 金沢大学高度モビリティ研究所 / 金沢大学理工研究域機械工学系 日本機械学会 = The Japan Society of Mechanical Engineers 2010-10-01 2017-10-03 jpn journal article VoR https://doi.org/10.24517/00008217 http://hdl.handle.net/2297/26392 https://kanazawa-u.repo.nii.ac.jp/records/8230 10.24517/00008217 AN00187463 0387-5024 Nihon Kikai Gakkai Ronbunshu, C Hen/Transactions of the Japan Society of Mechanical Engineers, Part C 76 770 2621 2627 https://kanazawa-u.repo.nii.ac.jp/record/8230/files/TE-PR-TACHIYA-H-2621.pdf application/pdf 309.2 kB 2017-10-03
