摘　　要：针对当前篮球训练中缺少量化计算的问题,开发了篮球训练仿真系统。首先利用篮球运动轨迹方程求导,得到起落点不在同一水平线上的无空气阻力情况下最佳出手角和出手速度的精确解。实验表明最佳出手角随出手速度的增加而增加,随出手高度的增加而减小。当投篮距离增大时,最小出手速度需要增加,最佳出手角则减小。然后制作了可视化的仿真环境,并对运动员动画、有物理材质的篮球、声音模块、关卡设计、最佳出手角计算模块及网络计分系统等进行了研究。运动员可以利用该可视化环境测算适合自己的最佳出手角和出手速度,辅助训练。In view of the lack of quantitative calculation problems in the current basketball training, the basketball training simulation system was developed. The exact solution of the best shot angle and velocity of shots without air resistance is solved using the trajectory equation of basketball movement whose start and end point are not in the same level. The result shows that the best shot angle will increase with the increasement of the shot speed, decrease with the increasement of the shot height. With the increasement of the shot distance, the minimum shot speed need to be increased, and the best shot angle is decreased. At the same time, a visual simulation environment is created which includes the animation of athletes, the basketballs with physical material, sound, level design, the best shot angle calculation module and network scoring module. Players can use the visual environment to measure the best shot angle and shot speed for auxiliary training.
