摘要
提出在汽车乘员约束系统中增设座椅坐垫倾角调节机构,在汽车正面碰撞前或正面碰撞中增大座椅坐垫与车身地板的夹角,利用座椅坐垫在乘员的重心前方形成有效约束,从而减轻乘员伤害的设想。为此,以某型轿车驾驶区相关尺寸参数和性能参数为依据,采用MADYMO分析软件建立汽车正面碰撞仿真分析模型,并经试验验证。采用不同座椅坐垫倾角进行仿真分析,结果表明,当采用25°座椅坐垫倾角时头部损伤下降21.4%,胸部损伤下降16.6%,而髋部损伤仅仅增加8.2%,腿部损伤依然较低。因此,在汽车乘员约束系统中增设座椅坐垫倾角调节机构能够有效地减少乘员的伤害。
An assumption is brought, that is, by using seat cushion to make effective restraint in front of occupants’ center of gravity, and adding seat cushion obliquity adjusting instrument to increase the angle between seat cushion and floor of car body before or during front collision, occupants’ injury can be reduced. Therefore, based on the correlation size of a certain car and performance parameter of driving region, MADYMO analysis software is used to establish the simulation model of automobile front collisi...
