Analysis of Factors Causing Occupant Hip Joint Injuries in a Crash Using Human Body Models.

Abstract

According to the field data in Japan, pelvis and extremities account for more than 50% among those seriously injured in crashes. In this study, based on medical data such as treatment costs and treatment periods, hip joint injuries, resulting in residual disorders were focused. The goal of this study is to analyze the factors that cause hip injuries under various loading conditions using human body models with improved anatomical structures and material properties around the hip joint. As a result, it was suggested that the sitting posture of the occupant and impact direction affect the hip joint injury.
