Optimization Method of Seat Back Modeling Surface Based on Whiplash Performance
To reduce the damage of whiplash injury in low speed rear-end collision,an optimization method of seat back modeling surface is proposed and its influencing mechanism on headback clearance is discussed.Based on the method,the whiplash performance of a certain seat is optimized and verified through experiments according to CNCAP procedure.The results show that the proposed method has less influence on seat modeling,the optimization objective is in good agreement with the experiment results,and the injury value of dummy neck decreases by 16.6％,a significant reduction for both upper neck load and lower neck load.
