人体运动仿真建模方法研究

为了研究人体在运动过程中的力学行为,探讨人体运动仿真的建模方法,运用多体系统动力学的建模方法建立了17刚体,55自由度的人体动力学模型,模型对人体颈部和下躯干的柔性效应给予了充分考虑,基于第一类Lagrange方程推导了系统的动力学方程,并以某人体为例,利用该模型对人体的行走过程进行了仿真计算,计算结果表明:采用所建立的人体动力学模型进行人体步态仿真、碰撞仿真等研究是现实可行的,最后结合对人体运动仿真的未来发展趋势的展望,说明人体动力学模型有待进一步完善.

Modeling Methods for Simulation of Human Motion

To study the modeling methods for simulating human motion,a 17-rigid-body human movement model is established by using multibody dynamics theory.The degree of freedom of the model is 55.The flexible effect of neck and lower torso is considered.The system equations are formulated based on the 1st Lagrange Equations.The locomotion of some human body is simulated as an example.The solution results demonstrate that this model can be applied to the simulation of human gait and impact.However,the human movement m...
