摘要
通过风洞实验对在不同风速下以及是否对称的球的飘晃距离和飘晃特点进行研究,得出以下结论:随着风速的不断增大,飘球产生的飘晃距离呈现先增大后减小再增大的现象,并在10～15 m/s时达到最大;对称球和不对称球在飘晃距离上差异不明显,只是在飘晃特点上有所不同.
By the wind tunnel experiment, according to different wind speeds and whether the ball was symmetrical or not, a research into the volleyball floating distances was carried out, and the conclusion was drawn as follows. 1. With the increasing wind speed, the floating distances of the ball would increase at first, then would decrease before the last increment, and the maximums distances would be 0. 5～0. 6m at the speed of 10～15m/s. 2. Whether the ball is symmetrical or not, the differences of floating distances were not apparent, and the only difference was in the floating characteristics.
