In order to improve the safety score of the driver's side airbag under the side pole collision condition,the model of occupant's restraint system in the vehicle side pole collision was built according to the 2021 version of C-NCAP,and the vehicle collision and simulation results show that the safety scores of the head,abdomen and pelvis all reach the standard,and the chest injury is more serious and the score is lower.By optimizing the pouch shape and stomatal diameter of the side airbags,the chest rib safety score is improved.The optimization results show that the compression of the upper rib,middle rib and lower rib of the chest decreases by 30.97%,8.26%and 13.71%,respectively,which verifies the effectiveness of the optimization scheme.
