Development of Cyber Dummy for Evaluating Human Body Damages in Seismic Hazards

Abstract eng:
One of the most important problems in investigations of natural disasters such as earthquakes and man-made disasters such as collisions between automobiles or ships or accidents involving crowds is to elucidate the mechanisms underlying injury or death. The ultimate purpose of this research is to present the development of a finite element anthropometric model (cyber dummy) that provides more accurate data about trauma than the current crash dummies used in automotive safety engineering. Ethical issues and the complicated shapes of the parts of the human body are considerable obstacles to the creation of cyber dummies. In this research we propose a procedure for transforming data and producing finite elements to create just such a model. Commercially available anthropometric data (DXF format) is processed, enabling closed spline curves to be used to fit the morphology of any given body structure. These closed spline curves are then automatically meshed in a standard application for producing a finite element model. The resulting solid model can be used to analyze trauma incurred during events such as collisions.
