摘　　要：为提高侧面柱碰撞工况下驾驶员侧气囊安全得分,依据2021版C-NCAP管理规则搭建汽车侧面柱碰撞乘员约束系统模型,实车碰撞及仿真结果表明,头部、腹部、骨盆安全得分均达标,胸部伤害较严重,得分较低。通过优化侧气囊的袋型和气孔直径,提升胸部肋骨安全得分。优化后结果表明,胸部上肋骨、中肋骨、下肋骨压缩量分别减小30.97%、8.26%、13.71%,验证了优化方案的有效性。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.
