摘　　要：在未来智能车辆乘员坐姿多样化发展的趋势下,针对第50百分位男性假人建立车辆约束系统的MADYMO多刚体仿真模型,根据实车碰撞试验数据验证其可靠性,并利用该模型将乘员坐姿划分为5种类型,研究汽车正面碰撞条件下除标准坐姿外的4种假人坐姿在自动紧急制动(AEB)系统与主动安全带共同作用下对假人损伤风险的影响,分析假人头部和髋部的合成加速度,以及假人各部位的受力情况。结果表明:不同坐姿对乘员产生的损伤不同,相对于标准坐姿,其他坐姿条件下乘员头部加速度均有所提高。In view of the diversified development of occupants’sitting postures of intelligent vehicles in the future,vehicle restraint systems MADYMO multi-rigid-body simulation model was set up for the 50 percentile male dummies,and its reliability was validated according to the real vehicle crash test data,and then the occupants’sitting postures were divided into five categories through the model.And the influence of the combination of Autonomous Emergency Braking(AEB)system and seat belt on the dummy’injury risk of four kinds of dummy sitting postures except for the standard sitting postures in frontal crashing was studied.The synthetic acceleration of the head and hip of the dummy and the force of each part of the dummy were analyzed.The results show that the occupant restraint system with standard sitting posture can improve the head acceleration of occupant with different sitting posture,and different sitting posture will cause different injuries.
