摘要：
The occupant leaning forward will increase the human injury risk under collision conditions after vehicle braking . In this paper，occupant out of position effect and parameter optimization analysis and research are carried out under the pre-collision braking.The forward displacement interval of the occupant's neck under different braking conditions is obtained through the real vehicle braking test. The MADYMO active human body simulation model is established. The variable analysis method is used to study the characteristics of occupant out of position with different braking waveforms. The orthogonal design method is used to conduct sled impact test to obtain the influence of the occupant dislocation factor on the occupant collision injury. The occupant response surface model is established ，using the central composite test design（Central composite design）method to study the correlation between the active seat belt parameters and the occupant's forward displacement out of position，and the optimal parameter combination is obtained by optimizing the design. © 2023 SAE-China.
