The study aimed at optimizing the anti-whiplash performance of the seat in rear impact by using orthogonal experimental design (OED) and comprehensive equilibrium methods. Firstly, according to the Euro NCAP evaluation procedure for whiplash injury, a rear impact model was developed with BioRID II dummy, sled system, seat and seat belt by using MADYMO code. Then, the anti-whiplash performance of the seat was evaluated by using five criterions (NIC, Nkm, etc). In order to improve the anti-whiplash performance of the seat, the effects of 7 design parameters (the position of the headrest, the stiffness of the headrest, etc) on the five criterions was analyzed. The results from the study show that NIC is reduced by 36.8%, and other four criterions are also decreased in the best configuration.
