摘要
本文报告了以伞兵为对象,利用高速摄影和仪器分析方法,对采用半蹲式和侧滚式两种姿势,模拟跳伞着陆时人体主要节段承受的冲击过载进行了比较。实验结果表明,从减少人体主要节段承受的冲击过载看,侧滚式姿势优于半蹲式姿势。
This is a study on the impact loads coming from half-squat and side
spin landing postures imposed on the major segments of human dody.
The subjects were three young and healthy male parachuters.They were
exposed to the impact induced by simulated parachute jumping and landing
in the laboratory.High-speed photography and apparatus analysis were
used.The experimental results showed that in terms of reducing landing im-
pact load acting on the major segments of human body,side spin posture
was better than half-squat one.
