Abstract: Procedures for studying the dynamic response of the occupant within a rear‐end impacted vehicle are presented. Most of the researches in the impact analysis were performed by experimental approach and this costs a lot of time and money. Especially, the repeatability is very hard to produce in a destructive condition. Most of all, the analytic parameters can be investigated are limited by the experimental approach. By using numerical techniques, this research employs Kane’s equation and Huston’s method to develop a simulated system with visual graphic output to observe the rear‐end impact response. According to the simulated results, at a constant seatback angle the maximum acceleration values of head and chest increased with the increasing of impact velocity. Furthermore, at a constant impact velocity the relative rotation angle of a passenger’s head to chest decreased with the increasing of initial seatback angle.
