| 摘 要： | 本研究了在弹射救生中，飞行员未脱手时上肢的受力状况，以及脱手以后上肢的自由甩打运动。建立了上肢三刚体七自由度的模型，用虚位移原理建立了脱手前上肢约束力的方程，用Ｋａｎｅ方法建立了脱手后上肢自由甩打运动的动力学方程，研究了各种弹射状态下上肢的受力情况及上肢的运动规律。

| Abstract: | During aircraft escape ejection, the force and the movement of pilot's limb before and after his hands slipping out of the center ring are studied. A 3-body model of limb is established by using principle of the virtual displacement and Kane's method. The force and movement are obtained under some aircraft escape ejection conditions. |

| Keywords: | aircraft escape ejection upper limb principle of the virtual displacement Kane's dynamic equations. |
