Abstract

Abstract:

A side impact sled test of a certain vehicle model was carried out to gain an deeply understanding of the response differences of different occupant genders in the collision process of far side occupant protection based on Euro NCAP 2020 far side occupant protection test and evaluation procedures. Based on the movement and response principle of the occupants, the differences of the injury situation and response time between male (WorldSID 50th) and female (SID IIs 5th) occupants were compared and analyzed. The results show that the maximum bending moment of the lower neck of the SID IIs 5th female occupant is about 2.2 times that of the WorldSID 50th male occupant, and the average abdominal compression deformation of the female occupant is about 50% smaller than that of the male occupant; the 3 ms composite acceleration of the female occupant's head, and the response time of the neck bending moments are about 12 ms earlier than that of male occupants. This research provides effective technical support for the further development of the side impact far side occupant protection scheme in the future.
