摘要
将人体的运动简化为由四个刚体组成的链状多刚体系统的平面运动,接Kane方法建立了由4个刚体铰接的四自由度的人体运动的动力学模型,通过四阶Runge-Kutta方法求解方程可以得到在不同时刻人体各部分的运动状态、摔倒时地面的冲击力、损伤机率,并依此对运动损伤作出预测,从而对损伤的防治有着一定的指导作用.
Human gait was simplified as a four-hinged-rigid-body-system horizontal movement, thus established the dynamic model according to Kant method. By using Rungc-Kutta method to learn about the motion state of human body, shock power of falling down onto the ground and damage probability at different moments, the athletic injury can be predicted, which provides certain guidance on the prevention and treatment of athletic injury.
