关于跳台跳水体型系数设置的建模分析

Modeling and Analysis on the Setting of Body Shape Coefficient in Platform Diving

为了研究跳水运动员的体型是否对跳水成绩有影响,应用物理学方法,建立了耦合非刚体动力学模型,得到跳水时间与身高,体重的函数关系式,利用函数对身高,体重的偏导数给出了体型校正函数,并对部分跳水动作的难度系数进行了校正,结果与实际相符.

In order to study whether the diver’s body shape has an effect on the diving performance,a coupled nonrigid body dynamics model is established by using physical methods.The functional relationship between diving time and height,weight is obtained.The body shape correction function is given by using the partial derivative of height and weight,and the difficulty coefficients of some diving movements are corrected.The results are in accordance with the fact.
