人—板系统模型（Ⅰ）：基本运动方程

Human-Board System Model(Ⅰ):Basic Movement Equation

利用力学和数学理论与方去，将跳板简化成一悬臂梁，将人体简化成由质点和无质量刚性细杆通过铰相连接而成的模型，建立了人一板系统数学模型的基本运动方程，利用该模型有利于分析人体与跳板这一耦合系统的自然规律，为进一步的运动仿真、运动技术诊断、运动优化以及有关理论研究奠定良好的基础。

In this paper,by the method of mathematics and mechanics,basic equation of mathematical model about human-board system were established by simpling human and board. This model can be used to analgse human-board coupling system. Further this model is basic for simutation、sports dialog sising and optimum etc.
