The investigation of automotive accident injuries

An investigation of Elderly Occupant Injury Risks based on Anthropometric Changes compared to Young Counterparts

Abstract: The study investigated the injury risks of two elderly occupants compared to a young occupant in frontal crashes using Finite element modeling. The results demonstrated that the injury mechanisms in the elderly are combinedly governed by changes in anthropometry and material properties. The altered injury risks among the elderly were in line with the field data analysis. Thus, for the investigation of injuries and the development of countermeasures, the anthropometric changes and the material properties of the elderly should be taken into consideration.

Comparison of small female occupant model responses with experimental data in reclined posture

Abstract: The reclined posture is most favored in the upcoming autonomous vehicles. The small females are hypothesized as well as demonstrated to be susceptible to submarining in reclined postures. The current study demonstrated the importance of anthropometric details that alter the kinematics in these updated postures. The objective of this study was achieved by developing a subject-specific occupant model comparing the response with the test data and the standard small female model. The subject-specific model showed a superior correlation to the test data. Thus, the anthropometric details govern the submarining and thus the injury responses in small females in the reclined postures and should be incorporated in FE models to reproduce kinematics and injury mechanisms.
