【摘要】 侧面帘式安全气囊在汽车碰撞事故中发挥着保护人体头部免受或减轻受伤害的重要作用,为了最优地发挥安全气囊的保护功能解决这一问题,提出采用降低头部最大瞬时加速度为优化目标,选定五个关键的参数在汽车被撞发生后发生爆炸的时间进行单目标优化设计。仿真计算利用经美国国家高速公路管理局（NHTSA）验证后的Dodge Neon有限元汽车模型和假人模型(50^thpercentile dummyⅢ)进行仿真计算,并利用RSM方法对安全气囊进行优化设计。最优化结果表明,所采用方法能进一步地提高侧面帘式安全气囊的保护功能。更多还原

【Abstract】 In this study,we conducted a single-objective optimization with finite element analysis in the occupant safe design for side impact crashworthiness considering the peak head acceleration.A full-scale finite element vehicle model of a 1996 Dodge Neon,with a curtain airbag and a dummy model,was used in simulating the side impacts.Based on an analysis of the injury for the dummy head,five parameters are selected as the design variables for the single-objective optimization.Also,the first and second-order polynomials are carried out to do comparison in creating the metamodels for the objective and constraint functions.The optimization results show that the peak head acceleration can be significantly reduced by optimal position of the side curtain airbag and optimum parameters of side curtain airbag for using second-order polynomials.更多还原
