Abstract: The objective of this study is to simulate the dynamic response of the human body within a rear-end impacted vehicle. The earlier biodynamic computer model, Supercrash, is modified to perform the analysis. The results show that, at a constant impact velocity, the relative rotation angle of an occupant's head to chest decreased with an increase of initial seatback angle. Furthermore, at a constant seatback angle, the maximum acceleration values of head and chest increased with the increase of impact velocity.
