为探讨在弹射座椅上装有限臂板时人体上肢对气流吹袭的耐受限度，使用弹簧驱动的撞击试验机，对１３具人尸体上肢和７只活猴的上肢进行冲击试验。获得了在限臂板约束下，冲击力、肘关节力矩与上肢损伤的关系；获得了关节生物力学特性曲线与临床损伤的分级关系，探讨了从人尸体、猴的实验结果换算到活人的可行性。结果表明，在限臂板防护下，上臂的耐限比前臂的高；人体前臂冲击力安全限为１．２６ｋＮ，肘关节力矩为１７９．５Ｎｍ。
In order to investigate the tolerance of the human upper limbs to air currents when a restricted arm plate was installed on the ejection seat, a spring-driven impact test machine was used to impact the upper extremities of 13 human corpse upper limbs and 7 live monkeys. Obtained under the constraint of the limit arm plate, impact, elbow torque and the relationship between the upper limb injury; access to the biomechanical characteristics of the curve and the clinical damage grading relationship, from human cadaver, monkey experimental results converted to living feasibility. The results show that under the protection of the limit arm plate, the upper arm has higher resistance than the forearm; the safety limit of human forearm impact is 1.26kN and the elbow torque is 179.5Nm.
