摘要

本研究目的是探討兩支不同構造方式網球拍動力學振動響應。研究以Wilson Hyper Carbon Triad 4.0及Wilson Hyper Carbon Pro Staff 5.0網球拍為研究對象。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為60磅。實驗方法為衝擊實驗法，使用衝擊球唧吸器咬住衝擊球於100公分高度，以自由落體的方式碰撞拍面朝上，水平鉗鋏於測力板的網球拍，應用運動生物力學分析軟體，蒐集及紀錄每支球拍各十次之碰撞實驗資料。實驗所得訊號資料，使用頻譜分析的方式加以整理分析。研究結果發現：一、Wilson Hyper Carbon Triad4.0網球拍在振動響應時間優於Wilson Hyper Carbon Pro Staff 5.0網球拍。二、Wilson Hyper Carbon Triad 4.0網球拍在總振動功率優於Wilson Hyper Carbon Pro Staff 5.0網球拍。

The purpose was to examine the vibration response of the Different Construct Types tennis racket through the impact experiments. The study was used to Wilson Hyper Carbon Triad 4.0 racket and Wilson Hyper Carbon Pro Staff 5.0 racket respectively. Two various rackets were strung Fiber Tech style string that the string tension was 60 pounds. The vacuum was used to drop impact ball from a distance of one meter at centric location of racket. The Vibration response data of two various tennis rackets were not only recorded through force transducer of Kistler Force plate and Bio ware but also used Spectrum Analysis.The result of this study was show: (1) The Wilson Hyper Carbon Triad 4.0 racket had the shortest the settling time of vibration response. (2) The Wilson Hyper Carbon Triad 4.0 racket had the lowest vibration response.
