1A1-G10 Effects of Falling Conditions on Injury Estimation by Collision and Fall using Life Support Robot(NEDO Project for Practical Applications of Service Robots)

Abstract

This paper describes studies to understand the fundamental mechanism of the collision and fall induced human injury by using dummy in the experiment. In our dummy experiments, the dummy on the platform is collided by the other dummy and fallen on the floor. It is concluded that the injure criteria such as HIC, Nij, Ac, Dc, AIS, ISS were effected by the initial position and pose of dummy. Especially, HIC (Head Injury Criteria) decrease under the safety area with helmet in all cases of these dummy experiments, and Acs for all cases are over the threshold level. It is strongly recommended that the ISS should be decreased with consideration of elder ages.
