| 中文摘要 | 建立了人体上肢3刚体7自由度的多刚体模型,并应用Kane方法建立了上肢鞭打动作的物理模 型,计算出上肢各环节在鞭打动作过程中的肌肉力矩和关节反作用力.实践证明,Kane方法在描述和计算上 肢运动的形式和力矩时具有列解方程规范简洁、编程计算方便高效的特点,计算结果能够反映动作实际.通过 对棒球投掷动作上肢三个环节力和力矩进行计算与分析,初步了解了上肢各环节在运动过程中肌肉力矩和关 节反作用力与动作技术的关系.; Upper limb whiplash movement (ULWM) is one of the most important skills in many kinds of sports. A model of a three-segment kinetic chain consisting of upper arm, forearm and distal segment was established for kinetic calculation. Kane's method was used to get the resultant muscular moment and Newton's method to get the joint reaction force. It can be concluded that Kane's method can describe the upper limb model movement. And be used to calculate the muscular moment efficiently. The upper limb movement in baseball pitching was studied by this model and some relationships were found between reaction forces and kinetic data. |
