ロボットによる轢過に起因した中足骨の骨折耐性の推定手法

抄録

Human foot injury due to being run over by a robot is a hazardous event caused by robot motion and should be considered in risk assessments prior to designing robots. This study aims to provide information on the human foot injury tolerance for risk assessments. A method to predict the human metatarsal fracture tolerance by scaling the fracture forces of alternate specimens (bear metatarsals) to those of human metatarsals is proposed. A scaling parameter based on the assumption that a metatarsal is represented by an elastically supported beam is discussed. The validity of the method is examined by fracture tests and size measurements of bear metatarsals.
