儿童航空安全装置对1.5岁儿童保护效果研究

Research on the protective effect of aviation child safety device on 1.5-year-old children

儿童航空安全装置(ACSD,aviation child safety device)是专用于商用飞机上的儿童约束系统。目前,中国民航主要使用附加环带作为儿童航空安全约束装置,但缺乏其对儿童保护效果的定量分析。本文基于16 g水平冲击滑台试验,研究Q1.5假人在附加环带和CARES(child aviation restraint system)安全带两种儿童航空安全装置约束下的头部、颈部、胸部和腹部损伤情况。结果表明:在规定的试验工况下,CARES能有效约束和保护1.5岁儿童,而附加环带会对儿童颈部和腹部造成严重损伤。该研究可为儿童航空安全装置的使用提供参考和指导。

Aviation child safety device(ACSD)is a child restraint system specially designed for commercial aircraft.At present,the supplementary loop belt is mainly used in civil aviation in China as restraint device of children aviation safety,but the quantitative analysis of its protective effect on protecting children is still lacking.Based on the 16 g longitudinal impact sled test,the injuries on head,neck,chest and abdomen of the Q1.5 dummy under constraints of two types of ACSD including the supplementary loop belt and the child aviation restraint system(CARES)safety belt are studied respectively in this paper.The results show that under the specified test conditions,CARES can effectively restrain and protect 1.5-year-old children,while the supplementary loop belt will cause serious injury to neck and abdomen of the children.This study could provide reference and guidance for the use of ACSD.
