| 摘 要： | 建立了带正确使用条件的4种类型儿童座椅(利用车辆座椅安全带锚固的5点式背带型、护板型和着衣型及采用ISOFIX锚固的5点式背带型)正面碰撞台车试验有限元仿真模型,并分别进行仿真和试验校验.接着采用同样的有限元模型进行误使用条件下的仿真分析.结果表明,4种类型儿童座椅在误使用情形下的假人伤害值都比正确使用情形时大;而采用ISOFIX锚同的5点式背带型儿童座椅的保护性能比其他3种类型更优越.

| Abstract: | Finite element models for frontal crash sled test simulation of 4 types of child seats(the 5-point harness type,tray shield type and wearable type anchored on car seatbelts and the 5-point harness type with ISOFIX anchorages) under correct condition of use are set up with corresponding simulations and test verification proceeded.Then another batch of simulation is conducted using same models mentioned above but with conditions of misuse.The results show that the injury severities of child dummy in all 4 typ... |
