To obtain tolerance limit of human upper extremity with arm restraint plate on eject seat to windblast, impact was applied to the upper extremity of 13 human corpses and 7 living monkeys by a spring driven impact device. Relationship between impact load, moment of elbow joints and arm injuries with arm restraint plate were studied. Relationship between biomechanical characteristic curve of human elbow joint and clinical injuries was obtained. The results indicated that tolerance limit of human upper arm is higher than forearm. Safety limit of human anterior arm to simulated aerodynamic load is 1.26 kN.
为获得弹射座椅上带有手臂约束板的人体上肢对爆风的耐受极限，通过弹簧驱动冲击装置对13具人体尸体和7只活猴的上肢施加冲击。研究了带有手臂约束板时冲击载荷、肘关节力矩与手臂损伤之间的关系。得出了人体肘关节生物力学特征曲线与临床损伤之间的关系。结果表明，人体上臂的耐受极限高于前臂。人体前臂对模拟气动载荷的安全极限为1.26千牛。
