摘要

裸弓射箭的射击风格将稳定系统限制在连接到立管的重物上,立管是弓的中心部分。没有科学研究可以指导光弓弓箭手选择最佳重量配置。在接下来的工作中,制定了一种以人为中心的方法,从科学和面向用户的角度解决这一问题。所提出的方法基于主观指标(弓箭手使用设备的感觉)、客观指标(可测量的数量)和精度。该研究寻求主观和客观指标之间的相关性,以深入了解弓的配置问题。考虑了11种重量配置。在船头的五个位置测量振动,并使用惯性测量单元测量3D动态运动。七名射箭运动员完成了一份问卷调查,以评估主观射击感觉。结果表明,两种最佳重量配置是250–200 g和350–200 g、 分别在中央和下部附接点处。弓的振动水平与弓箭手与射击相关的感觉之间,以及弓的动态运动与射击的舒适性之间存在着强烈的相关性。在振动时间和弓箭手的身体感觉之间没有发现相关性。确定重量配置对射击精度的影响具有统计学意义,需要为每个重量配置发射不切实际的大量箭头。开发了一种新的方法来将弓箭手的身体感觉与可测量的参数相关联,并将其应用于理解裸弓重量选择问题。这种方法可以进一步发展,以关联额外的主观和客观指标。对这些相关性的理解将允许在设计过程中模拟的客观指标用于确保最终设计对主观指标的满意度。

Analysis of preferred weight configuration for barebow shooting style
The barebow archery shooting style limits the stabilisation system to weights connected to the riser, which is the central part of the bow. No scientific study is available to guide the barebow archer in the choice of the best weight configuration. In the following work, a human-centred methodology was developed to address this problem from both a scientific and user-oriented perspective. The proposed methodology is based on subjective metrics (archers’ sensations using the equipment), objective metrics (measurable quantities) and precision. The study sought a correlation between the subjective and objective metrics to provide insight into the problem of configuring a bow. Eleven weight configurations were considered. The vibration was measured at five positions on the bow and the 3D dynamic motion was measured using an inertial measurement unit. Seven archers completed a questionnaire to evaluate the subjective shooting sensations. The results show that the two best weight configurations are the 250–200 g and the 350–200 g, at the central and lower attachment points, respectively. A strong correlation exists between the vibration level of the bow and the feeling archers associated with the shooting, and between the dynamic motion of the bow and the comfort of the shooting. No correlation was found between the vibration time and the physical sensations felt by the archers. Determining the influence of the weight configuration on shooting accuracy, with statistical significance, would require an impractically large number of arrows to be shot for each weight configuration. A new methodology was developed to correlate the archers’ physical sensations to measurable parameters and this was applied to understand the barebow weight selection problem. This methodology could be further developed to correlate additional subjective and objective metrics. An understanding of these correlations would allow objective metrics, which can be simulated in the design process, to be used to ensure satisfaction of subjective metrics by the final design.
