摘要
通过建立中远距离投篮的三维物理模型,利用matlab数值计算方法得到了中远距离定点投篮过程中,能够使篮球空心入筐的出手状态对应的物理参数相空间,并由此得到了投篮最佳出手速度与角度,以及最佳入筐角度随出手距离、出手高度的变化规律。中远距离投篮过程中瞄准点在篮筐中心之后7 cm附近,几乎不随出手距离、高度的变化而改变。
In this paper,a physical 3D model is developed,which suggests a pathway to determine the optimal release conditions for a middle-long distance set shot.In this paper,by using MATLAB numerical calculation method,the phase spaces corresponding to the release conditions for clean shot in the process of middlelong distance set shot is obtained.The relationship among the parameters is revealed,including speed of the shot,the shooting angle,and the optimum angle of entry,and the shooting distance and height.The optimal target point is at 7 cm behind the center of the hoop,nearly unchanged with different shooting distance and height in middle-long distance shots.
