摘　　要：针对目前传统的小倾角及新兴的大后倾角弹射座椅,基于人体测量学相关数据,以50百分位数中国男性飞行员为例,建立简化人体模型并进行受力分析,求解人体在过载瞬间所受的弯矩及轴力,得出同等冲击水平下,大后倾角弹射座椅对人体冲击小于小倾角座椅的结论,并利用Jack软件进行模拟,验证了仿真计算所得数据的准确性。Aiming at the traditional small angle ejection seat and burgeoning large angle ejection seat, this paper took the 50 percentile Chinese male pilots as example, and built simplified human model to analyze the force based on anthropometry data. When calculate the bending moment and axial force at overload moment, a conclusion can be drawn that the large angle ejection seat produces less impact than the small angle at same impact; then simulation was carried out in Jack software to guarantee the validity of data.
