摘要
本文在Hanavan人体模型的基础上 ,对人体模型进行了简化 ,建立了由 4个刚体组成的人体模型 ,并利用动力学原理建立了跳板跳水的人 -板多刚体系统 ,提出系统的控制函数并给出系统解体的一个充要条件。最后利用计算机仿真 ,仿真出各参数对系统输出的影响 ,从而为技术诊断和修正提供依据。
Based on the Hanavan human body model, the simplification of human body model is conducted. The human body model composed of four rigid bodies is established. With the principle of dynamics, the physical and mathematical models of the multiple-rigid-body systems of springboard diving man-plate system are also set up. The controlling function of the system is proposed. The adequate and necessary conditions of the system separation are also presented. Finally, the computer simulation of the system is carried out. The simulation results show how the parameters affect the outputs of the system, which provide the bases for further technical diagnosis and modification.
