摘要
研究了失重状态下人体的动力学方程．从动量矩守恒原理出发，应用矢量力学和多刚体动力学方法建立起失重状态下人体的动力学模型，所得方程是一阶的，适用于计算机编程．方程的求解只要求输入人体基本的质量特性参数和相邻肢体的运动控制规律．文末给出了一个航天员通过双腿的圆锥摆运动来改变其自身姿态的例子，并求得了解析积分式．
Dynamics equation of human in weightlessness was presented.On the base of vector dynamics,multi rigid body dynamics and the law of conservation of momentum,dynamics model of human in weightlessness was developed.The equation was one order and could be applied to computer easily.Only the parameters of human mass properties and the controlling regulations of the adjacent limbs were demanded for this equation.As an example,the conic motion of legs was analyzed and shown that an astronaut could change his posture by some limb′s motion,and an analytic integration solution of the motion was gained.
