智慧型纖維網球拍振動響應及回復係數分析

The Vibration Response and Coefficient of Restitution Analysis of Intelligent Fiber Tennis Rackets

摘要


本研究目的探討智慧型纖維網球拍動力學振動響應及回復係數。研究以Head i-prestige、Head Premier Tour網球拍爲研究樣本。每支球拍皆穿以P & F牌之Fiber Tech網球線,直線及橫線之張力皆爲60磅,並以衝擊實驗法加以實驗。實驗時使用衝擊球喞吸器將衝擊球於100公分高度,以自由落體的方式向心碰撞鉗頰於測力板上之網球拍,同時,應用運動生物力學分析軟體,蒐集紀錄每支球拍各十次之碰撞實驗資料,並應用高速攝影機紀錄衝擊球之反彈高度,所得資料使用頻譜分析及影片分析加以整理。實驗研究結果發現:增貼智慧型纖維網球拍在振動響應及回復係數皆較優於未貼智慧型纖維網球拍。

並列摘要


This study was to analysis the dynamically characteristics of the Intelligent-fiber tennis rackets through the impact experiments. The two various rackets Head i-prestige and Head Premier Tour were strung tension of 60 pounds with Fiber Tech style string. The vacuum was used to drop an impact ball from a distance of one meter at centric location of racket. The vibration responses and coefficient of restitution of the two rackets impacted by impact ball was studied via impact experiments. The data were not only recorded through force transducer of Kistler Force plate and Bio ware but also used Spectrum analysis. The experimental results show that: The intelligent-fiber tennis rackets in the view of the responses of vibration and the coefficient of restitution batter than un-used intelligent-fiber tennis rackets.
