摘　　要：为提高侧面柱碰撞工况下乘员的安全性,针对乘员在车速32 km/h侧面柱碰撞工况下的损伤进行了仿真分析。首先建立了侧面乘员约束系统模型并进行了可靠性验证,为改善侧面柱碰撞工况下安全气囊对乘员的保护效果,依据2021年版《C-NCAP管理规则》中侧面柱碰撞试验方法,搭建了车辆侧面柱碰撞规定结构运动(PSM)子结构模型,最后将试验与仿真结果进行对比,结果表明,合理的气囊形状、点火时刻及排气孔直径可有效提高乘员保护效果。In order to improve the safety of occupants in side pole impact,this paper analyzed the damage of occupants in side pole collision condition at 32 km/h by simulation.Firstly,a side occupant restraint system model was established and its reliability was verified.To improve the protection effect for occupant of side airbag and reduce the passenger’s injury in side pole crash,vehicle side pole crash PSM substructure model was established according to 2021 CNCAP Side-Pole test method.Finally,the test results were compared with simulation results,which show that the reasonable airbag shape,ignition timing and vent diameter can effectively improve the occupant protection.
