摘要
寻找出了副驾驶侧约束系统吸能与副驾驶乘员各部位损伤值的关系,为副驾驶侧约束系统优化提供了另一条思路。基于多刚体动力学分析软件MADYMO建立并验证了某车型正面碰撞副驾驶员侧约束系统的仿真模型。结合对正面碰撞中副驾驶员能量传递的分析,对副驾驶员约束系统吸能进行了研究,并得出各约束子系统的吸能曲线。基于30组实验数据对约束系统吸能与副驾驶乘员损伤值之间的关系进行了分析。结果表明:副驾驶测乘员伤害指标与约束系统吸收的乘员能量有较强的相关性;其中,加权伤害指标WIC、头部伤害指标HIC36、颈部剪切力FZ均与安全气囊吸能、安全肩带吸能成负相关;胸部伤害指标Ccomp、C3ms与安全肩带吸能成负相关;大腿轴向压缩力FL、FR和小腿的压缩力FZL、FZR均与护膝板和地板吸能成正相关。
The relationships between the energy absorption of the front passengers side restraint system and the damage value of the front passengers were found,which provided another idea for the optimization of the restraint system of front passengers.Based on the multi-rigid dynamics analysis software MADYMO,a frontal crash simulation model of front passengers’restraint system of a certain type of vehicle was established and verified.Combined with the analysis of the energy transmission of the front passengers in the frontal crash,the energy absorption of the front passengers’restraint system was studied,and the energy absorption curve of each constraint subsystem was obtained.Based on 30 sets of experimental data,the relationship between the energy absorption of the restraint system and the damage value of the passenger is analyzed.The results show that the front passengers injury index has a strong correlation with the occupant energy absorbed by the restraint system;among them,the weighted injury index WIC,the head injury index HIC 36,and the neck shear force FZ are negatively correlated with energy absorption of the airbag and shoulder belt;the chest injury indicators CComp and C3ms are negatively correlated with the energy absorption of shoulder belt.The thigh axial compression force FL,FR and the calf compression force FZL,FZR are positively correlated with total energy absorption of the knee guard and the floor.
