摘　　要：本文应用多刚体和有限元耦合的方法建立了3岁儿童乘员侧面碰撞仿真模型,并通过台车试验结果验证了模型的有效性。在此基础上,分析四种不同约束方案下3岁儿童乘员的动力学响应,对汽车侧面气囊、儿童约束系统引起3岁儿童乘员在侧碰撞中的损伤风险进行评估。研究结果表明:儿童约束系统和侧面气囊配合使用能大大地减少侧碰撞中儿童乘员的损伤风险,儿童约束系统单独使用时对儿童乘员的保护效果好过仅使用侧面气囊,而侧面气囊并没有增加儿童乘员的头部损伤风险,儿童乘员在无任何约束的情况下损伤风险最高。The CRS model and the rear door assembly model were developed by means of dynamic simulation of multi-body coupling with finite element method.The whole simulation model was validated in accordance with test.On the base of validated model,four simulation models were developed.Dynamic response of child dummy was analyzed to evaluate side airbag and CRS causing 3 year old child passengers injury risk in vehicle side impact.The results showed that CRS combined with side airbag could effectively mitigate injury risk of child passenger.CRS was more effectively than side airbag when used individually.However,side airbag did not increase child occupant injury risk in side impact.Child passenger had highest injury risk when they were not restrained.
