摘要

在汽车正面碰撞事故中，汽车座椅上的助推器滑动会影响儿童乘员的运动和伤害结果。本文研究了安全座椅滑动对儿童乘员下潜倾向及其他伤害风险的影响。在MADYMO平台上研制了一种6岁混合型假人的多体模型。利用该模型模拟了4种载荷情况，研究了滑动对儿童假人潜水和损伤结果的影响。研究表明，安全座椅滑动可以提高乘车效率，总体上对减少伤害有积极作用。当助推器滑动导致儿童撞击前排座椅的靠背时，或者如果儿童处于更斜靠的姿势，则有更高的沉没风险，它也有一些不利的影响。通过对儿童约束系统的优化设计，可以避免这些不利影响。

Effects of booster seat sliding on responses and injuries of child occupant

Booster seat sliding on vehicle seat can influence kinematical and injury outcomes of child occupant in frontal collision accidents. This paper presents a study of the effects of booster seat sliding on submarining tendency and other injury risks of child occupant. A multi-body model of the Hybrid III 6-year-old dummy positioned in a booster seat was developed on MADYMO platform. Using the model, four load cases were simulated to study the sliding effects on submarining and injury outcomes of the child dummy. The study has revealed that the booster seat sliding can increase ride-down efficiency and in general exert positive effects on injury reduction. It also has some unfavourable effects in cases when booster sliding causes the child to impact the seatback of the front-row seat or if the child is in a more reclined posture that has higher risk of submarining. The unfavourable effects can be avoided by optimising design of child restraint system.

期刊介绍： The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
