A series of +Gz impact tests were performed on the Armstrong laboratory vertical decelerator with human and manikin subjects wearing various helmet-mounted systems. The resulting data were used to quantify the effects on human dynamic response of varying helmet mass and seat acceleration as well as to provide comparisons to previously established safe limits of impact exposures. Tests with human subjects and a 97th percentile manikin were performed at seat impact levels of up to + 10 Gz for human and + 15 Gz for manikins, with standard and prototype helmet-mounted systems weighing from 3.2 to 6.6 lb. The results showed that increases in the helmet weight and seat acceleration resulted in increased compression, shear, and rotational forces on the neck. With helmet weights greater than 4.5 lb during +15 Gz impacts, neck compression force began to exceed established cadaver injury limits.
在阿姆斯特朗实验室的垂直减速装置上，对佩戴各种头盔安装系统的人体和人体模型进行了一系列 +Gz 冲击试验。所得数据用于量化头盔质量和座椅加速度变化对人体动态响应的影响，并与先前确定的冲击暴露安全极限进行比较。对人体受试者和第97百分位人体模型进行了试验，人体座椅冲击水平最高达 +10 Gz，人体模型座椅冲击水平最高达 +15 Gz，标准和原型头盔安装系统重量为3.2至6.6磅。结果表明，头盔重量和座椅加速度的增加导致颈部的压缩力、剪切力和旋转力增加。在 +15 Gz 冲击期间，当头盔重量超过4.5磅时，颈部压缩力开始超过既定的尸体损伤极限。
