在棒球、垒球和曲棍球运动中，运动员双手挥动球棒或棒子击打相对较硬的球。不恰当的撞击通常会导致一只手或两只手疼痛。实验模态分析揭示了对刺痛有贡献的弯曲模态振型。本文比较了在每个运动中引起刺痛的弯曲模态形状，突出了运动之间手的位置差异。两件式结构、材料选择和减震器已被用于减少金属和复合棒球、垒球棒和复合曲棍球棒的刺痛。将比较各种蝙蝠和棍棒成分的阻尼率。最近成功的减少刺在蝙蝠和棍棒使用减振器将讨论。
In the sports of baseball, softball, and field hockey a player swings a bat or stick held in both hands to hit a relatively hard ball. Poorly hit impacts often result in painful sting in one or both hands. Experimental modal analysis is used to reveal the flexural mode shapes contributing to sting. This paper compares the flexural mode shapes responsible for causing sting in each sport, highlighting differences in hand positions between sports. Twopiece construction, material selection, and vibration absorbers have been used to reduce sting in metal and composite baseball and softball bats and in composite field hockey sticks. Damping rates for various bat and stick compositions will be compared. Recent success in the reduction of sting in bats and sticks using vibration absorbers will be discussed.
