摘要
针对欧洲儿童乘员约束系统法规(ECER/4),以某款汽车儿童安全座椅为研究对象,使用非线性有限元动力学分析软件LS-DYNA进行了ECER/4动态试验环境下的碰撞过程仿真分析,得到假人头部加速度、头部损伤值HIC15及胸部加速度。通过与相应法规的比较,初步证明了该款儿童安全座椅的碰撞安全性。
Aiming at European Child Occupant Restraint System Regulations ( ECER/4 ) , the paper selects a child safety seat as object for analysis .It realizes the simulation of collision based on ECER/4 dynamic test envi-ronment in LS-DYNA, obtains an amount of related data such as dummy head acceleration , HIC and chest ac-celeration.Comparing with the ECER/4, it analyzes the collision safety performance of the child safety seat .
