歩行中のつまずき転倒現象の計測および危害推定

抄録

Relationship between the limitation of the fall avoidance motion and severity of the fall should be explained because the fall is one of the most severe risks in the industrial site. However, the study which recorded whole of the fall motion is rarely performed because of the difficulty of reproducing fall in the laboratory due to the safety concerns. In this study, the fall motion, which was caused artificially, was recorded as long as possible within the bounds of safety. Then, the successive motion until the ground contact was simulated. As a result, the position and velocity of the ground contact could be connected to the fall avoidance motion, which means the step length after tripping, and the motion during the fall, forward tilt of the body and vertical velocity of CoM.
