摘要

本研究的目的是提供儿童前腹部撞击的结构反应。九具未经防腐处理的尸体被分成两组。2-4岁的年轻队列(4具尸体)和5-12岁的老年队列(5具尸体)受到影响。撞击后进行了尸检。尸体试验的平均速度为6.3 m/s(±0.25 m/s)。老年组和青年组的平均峰值V*C值分别为2.53±0.59 m/s和1.98±0.41 m/s (p < 0.05)。青年组最大变形量为9.27±0.21 cm，平均峰值力为530.30±102.62 N，老年组最大变形量为9.88±1.50 cm，平均峰值力为929.16±133.24 N (p < 0.05)。八具尸体被发现，身上有不同的伤痕。良好的力-变形数据可以从尸体反应数据中得到，并且力/变形走廊已经为两个受试者群体得到。

Abdominal impact study on paediatric cadaveric subjects

The purpose of this study was to provide structural response of front abdominal impact in children. Nine unembalmed cadavers were divided into two groups. A young cohort aged 2-4 years (four cadavers) and an older cohort aged 5-12 years (five cadavers) were impacted. An autopsy was performed after the impact. The average velocity of the cadaveric tests was 6.3 m/s (±0.25 m/s). Mean peak V*C values were 2.53±0.59 m/s and 1.98±0.41 m/s in old cadaveric cohort and young cadaveric cohort respectively (p > 0.05). The maximum deformation and mean peak forces were 9.27±0.21 cm, 530.30±102.62 N and 9.88±1.50 cm, 929.16±133.24 N in young cohort and old cohort separately (p < 0.05). Eight cadavers were found with various injuries. Good force-deformation data may be derived from the cadaveric response data, and force/deformation corridors have been derived for both subject populations.

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.
