Abstract
This paper describes the difference of injury mechanisms between THOR FE model and Human FE model. The National Highway Traffic Safety Administration plans to introduce a new test method that uses RMDB and THOR. However, injury mechanisms of THOR dummy necessary for the development of occupant protection equipments are not explained enough. The injury values and injury mechanism of THOR dummy in oblique condition were compared with the human FE model (THUMS). Mechanisms of BrIC and Acetabulum Force were investigated in relation to the horizontal movement of THOR dummy.
