HUMAN INJURY EVALUATION USING HUMOS RADIOSS FINITE ELEMENT MODEL

In the context of road safety, dummies have been widely used as a mean to validate car developments in terms of occupant security. Nevertheless, these criterion showed limitation concerning the interpretation of injury. It induces the development of human body model. So, this paper consist to show how the Human Model for Safety (HUMOS) can be considered as a new tool to the definition of injury criteria in finding medical meanings of typical numerical validation tests. In a first part a general overview of the HUMOS model is presented. Then analysis of specific parameters of the HUMOS validation test was performed in order to show which parameters can be studied in a such numerical model to identify potential injuries on anatomical component. This paper shows how the HUMOS simulated human model can be used to provide an accurate description and understanding of human injuries. The HUMOS model of a simulated three-dimensional adult male in driving position has been validated on its isolated segments and on the whole model. It contains all internal organs as well as bones and skin, for all of which modeling parameters have been defined. Interpretation of injury data is enabled on several levels: the paper describes kinematics, showing the movement of parts of the body on impact; force and stress level which shows potential injuries to bone materials; and deformation and deflection measurements for soft tissue injury evaluation. The HUMOS model is a first step in the design of a European database of the finite element model of a human body.
