| 摘 要： | 鞭打动作是许多体育技术动作的重要组成部分 ,对鞭打动作技术的研究将对运动技术实践具有广泛而深入的指导意义。应用瑞典产 QUAL ISYS- MCU5 0 0红外远射测试系统 (6个镜头 )对羽毛球扣杀、排球扣球、标枪投掷、棒球投球动作过程进行测试。在一定简化的基础上建立了人体上肢 3环节 7自由度的环节链多刚体模型 ,应用多刚体动力学中的 Kane方法和红外远射测试系统所测运动学数据对上肢各环节运动的肌肉力矩进行计算 ,并应用隔离法计算上肢各环节在关节处的受力情况。通过对上肢鞭打动作技术进行运动学与动力学的综合分析 ,揭示了上肢在做鞭打动作时的空间运动规律与特征。

| Abstract: | Whiplash movement is the main component of many sport,there is comprehensive and significant meaning to study the whiplash movement.This paper makes test on movement of badminton and volleyball smashing,javelin throwing,baseball pitching through using the photoelectrical testing and analytical system of QUALISYS-MCU500 made in Sweden.A model of three-segment kinetic chain consisting of upper arm,forearm and distal segment is build for kinetic calculation.Using Kane method to get resultant muscular movement and using Newton method to get joint reaction force.Through analysis of kinematics and kinetics,this paper explains the characteristics and rules of upper limb whiplash movement. |
