Abstract

It is important to select reliable tools that archers should use in archery competitions. For this reason, we focused on the arrows among the tools and developed a shooting machine for selecting arrows. It is important to imitate the movement of the right finger to release the arrow and the forward movement of the bow after the arrow is released. Therefore, these factors were considered when designing the machine. In this study, a shooting experiment was conducted in which the shooting cycle of twelve ends of six arrows was repeated five times (one end is defined as six arrows). Next, using the data from the impact points on the target, specific arrows with a large dispersion were identified. Cluster analysis was then conducted to identify the arrows that showed a high similarity distribution. Based on the above results, we were able to identify arrows with the most flaws and select arrows that archers should use. The results indicate the effectiveness of the method of selecting reliable arrows by rejecting flawed arrows.

箭选射击机的研制

选择射箭运动员在射箭比赛中应该使用的可靠工具是很重要的。为此，我们专注于工具中的箭头，并开发了一种用于选择箭头的射击机。模仿右手手指松开箭头的动作和松开箭头后弓的向前运动是很重要的。因此，在设计机器时考虑了这些因素。在本研究中，进行了一项射击实验，其中六支箭的十二个末端的射击循环重复五次（一端被定义为六支箭）。接下来，利用目标上撞击点的数据，识别出具有较大分散度的特定箭头。然后进行聚类分析以识别显示出高相似性分布的箭头。基于以上结果，我们能够识别出缺陷最多的箭，并选择射箭运动员应该使用的箭。结果表明，通过剔除有缺陷的箭头来选择可靠箭头的方法是有效的。
