摘要
航天员在宇宙飞行上升、返回和着陆过程中,都会受到冲击力的作用。为了弄清不同束缚系统对人体耐力的影响,我们在垂直冲击塔上进行了人体实验(10G、120ms、等腰三角波)。实验记录的生理指标有心电、心率和体感诱发电位等。对测得的物理信号在美国HP5427信号处理机上进行冲击响应谱分析。结果表明,不同型号背带系统对人体耐受垂直位冲击力的作用是不一样的。
Impact deceleration is often encountered by astronauts during launch,
reentry and landing.In order to study effects of different restraint
harness on human tolerance,An experimental investigation was perfor-
med on a vertical impact tower with human subiects (10G,120 millise-
conds,iso-triangular).The physiologic indexes such as ECG heart rate
and SEP were recorded during the experiment.An American HP-5427
signal computer was used to analyzed the physical signals.The results
showed that different restraint systems had different effects on human
tolerance.
