30A-A-2 Falling, Cropper and Mechanical Human Injury(Biomedical Engineering Approaches to Human Senses and Errors)

抄録

Accidents of fall & descent sometimes cause serious injuries, which made us propose criterion-models of human biomechanical impacts when various robots would come into future daily life. The collision's experiments using dummy dolls, which were supposed to direct contact between human bodies and robots, were performed in co-operation with JARI. And theoretical models based on the experiments, which we thought to describe processes of the accidents of the fall & descent, were proposed. The worst case of the fall & descent in our daily life were assumed to be the fall & descent from on high, (chair, steps), and we attempted to estimate biomechanical Impacts and injuries by doing experimental image analysis. Finally, we found to be approximately expressed the fall & descent of human bodies as motions of ridged bodies and proposed a theory of rotation & free fall for human heads.
