摘要
按照C-NCAP对侧撞试验的要求,建立了某乘用车的侧撞有限元模型;设计了帘式气囊和胸部气囊系统,并通过MADYMO与LS-DYNA的耦合,进行了侧面约束系统的集成。以降低假人伤害为目标,结合试验设计方法,对侧面气囊的充气量、泄气孔大小进行参数优化。结果表明,优化后该车C-NCAP总分提高了4.18分,侧面气囊系统达到了明显的乘员保护效果。
According to the requirements of C-NCAP on side impact test, a finite element model for the side impact of a passenger car is built. A side impact airbag and a curtain airbag are designed and are then integrated into a side restraint system through MADYMO/LS-DYNA coupling. With reducing dummy injury as objective and combining the design of experiment, a parameter optimization is conducted on the inflation volume of airbag and the size of its drain hole. The results show that after optimization the C-NCAP score of the car increases by 4. 18 with the side airbag system achieving apparent occupant protection effects.
