摘要
基于自动紧急制动系统,对乘员动态响应及损伤值的影响进行分析。自动紧急制动系统模型与约束系统MADYMO模型是基于NHTSA关于追尾碰撞的紧急场景与相应整车数模搭建而成。耦合模型基于以上两模型集成搭建,并且模型的有效性通过试验数据得以验证。研究表明:车辆匹配自动紧急制动系统后,乘员的头部3 ms加速度减小了8.6%,HIC36减少了18.3%,胸部压缩量减小了13.8%。
The influences of integrated restraint system,combining with the Automatic Emergency Braking（AEB） system,upon occupant posture and injury were studied in this paper.Based on the rear-end crash test scenarios for NHTSA and vehicle geometry data,both AEB system model and the MADYMO simulation model were built up.After integrating these two models,the integrated model was built up and validated with certain experiment data to ensure its accuracy.The study indicated that the maximum head3 msacceleration could be decreased by 8.6%,the HIC36 could be decreased by 18.3% and chest compression could be decreased by 13.8%,after introducing the AEB system.
