翻转水瓶平稳落地现象的研究

Research on the phenomenon of water bottle flipping to the ground smoothly

本文对半满水瓶的翻转过程进行了理论与实验探究.通过对翻转过程中瓶内水的分布的简化假设,利用角动量守恒对水瓶翻转过程进行了理论分析.并且从实验上探究了初始角速度、加水量以及地面粗糙程度对水瓶平稳落地成功率的影响.

In this paper, the flipping of partially filled plastic bottle is investigated theoretically and experimentally.Through simplifying the distribution of the water in the flipping bottles, the movement of flipping bottle is analyzed theoretically by using the conservation of angular momentum.Then the effects of the initial angular velocity, the proportion of water in bottle and the ground roughness on the success rate of the bottle landing stably are investigated experimentally.Finally, a game advice is given.
