中文摘要：

分析了儿童的生理解剖学特征及不同身体部位的损伤机理，介绍了儿童头部和胸部的有限元模型建立及儿童假人模型的改进情况，提出了多功能儿童约束系统、集成式儿童约束系统等新的结构方案。仿真分析表明，这些结构能够对儿童乘员起到有效的保护作用。

英文摘要：

The anatomy of children＇s physical characteristics and iniury mechanisms were analyzed. The development of the child head and chest FE models and the improvement of the child dummy model were introduced. Then, two new kinds of child restraint systems （CRS）, multi-function system and integrated system, were proposed. Computational simulation results show that these two kinds of child restraint systems can provide effective protection for child occupants.
