摘要
本文建立了球体飞行时绕任意轴自旋情况下的动力学方程,分析球体在空气中飞行时的受力情况,并引入了风速影响,利用MATLAB软件编程对该动力学方程进行数值求解。以高尔夫球为例,考虑了顺风、侧风、逆风对轨迹的影响,分别计算模拟了球体在几种典型自旋情况下的飞行轨迹。本研究可为户外球类运动的理论研究提供一定参考。
This paper establishes the dynamic equation of the sphere spinning around any axis when flying,analyzes the forceof the sphere flying in the air,and introduces the influence of wind speed.The dynamic equation is solved numerically byMATLAB software programming.Taking golf as an example and with the influence of tailwind,crosswind,and headwind on thetrajectory considered,the flight trajectory of the sphere under several typical spin conditions is calculated and simulated.Thisarticle can provide a reference for the theoretical research of outdoor ball sports.
