为探究多样化的乘员离位姿态对乘员碰撞损伤的影响,综合考虑多种乘员典型离位姿态,借助成熟乘员舱模型和假人模型进行了 1 800次正面碰撞仿真,结果表明,相对于标准姿态工况,典型离位姿态下的乘员损伤均有一定程度的增加:座椅靠背角度增大会导致乘员头颈部损伤水平提高,而使胸部损伤水平下降;自动紧急制动(AEB)系统制动强度的增大会提高乘员胸部损伤水平而降低头颈部损伤水平;乘员向右偏移工况均比向左偏移工况有更大的头胸部损伤水平。
Frontal Crash Injury Study of Typical Non-Standard Seated Occupants in Intelligent Vehicle
In order to investigate the effects of diverse occupant out-of-position postures on occupant crash injuries,a variety of typical occupant out-of-position postures were considered,and 1 800 frontal crash simulations were conducted with the help of a mature occupant compartment model and dummy model.The results show that the occupant will suffer more injury in typical out-of-position posture than the standard posture;the increase of seatback angle leads to the increase of occupant head and neck injury level,while the decrease of thorax injury level;the increase of braking intensity of Automatic Emergency Braking(AEB)system increases the occupant thorax injury level,while decreasing the head and neck injury level;the occupants'head and thorax injury level is greater in the rightward offset condition than in the leftward offset condition.
