研究的目的是能否通过使用计算机仿真方法去重构人体上肢在水平面上做快速运动时的轨迹 ,通过与实验结果的比较 ,进而探讨人体上肢在水平面上做快速运动时的控制策略 .首先建立了人体上肢在水平面上运动的生物力学模型 ,应用时间最优判据对上肢在水平面上做点到点快速运动时的轨迹进行了重构 ,并通过实验对重构结果进行了评估 .评估结果表明 :时间最优判据能够重构人体上肢在水平面上做快速运动时的手的轨迹 ,可以认为此判据是人脑体对手臂在快速运动情况下的一种控制策略的模拟||This paper studies the movement trajectory of a human hand can be reconstrueted with a computer when the man moves fast on a horizontal plane. Comparing the simulation results with those obtained in experiments we study the control strategy for the human upper extremity when the man moves fast on a horizontal plane. A biomechanical model of human upper exfremity was built. Based on the time optimal criteria the trajectory of a human hand was reconstructed.The reconstructed trajectory was compared with that obtained in experimento and the results show a good consistency.A conclusion is draum that the time optimal critria can be regarded as one of the contoal stratagies of the hand’s movement when the human upper extramity moves fast from point to point on a horizontal plane.
