| 摘 要： | 根据空气动力学原理和人体运动规律,设计了可产生3级风的大型模拟风洞。通过不同风速条件下嗒嗒球空气作用力和运动飞行轨迹的大型风洞试验,对嗒嗒球重量、羽毛长度、球体高度及原材料等技术指标进行反复修改和调整,研制出在三级自然风环境中仍能开展正常运动健身的防风嗒嗒球。

| Abstract: | Based on aerodynamic principles and kinesiologic rules,the large scale wind tunnel simulation which can produce gentle breeze is designed.Through large-scale wind tunnel tests under different wind speed,the air force and flight path of patter ball is tested.Technical indicators,such as the weight,feather length,height and material of the ball is repeatedly modified and adjusted.And the wind proof patter ball which can enable the people to do exercises with it in gentle breeze. |
