高爾夫球為當今最熱門的運動項目之一。隨著高爾夫球這項運動
的熱門度提高，高爾夫球具的銷售度也隨之提高。而選擇高爾夫球具
的指標，不單只是尺寸大小或是揮擊性能而已，擊球音效也漸漸的被
列為購買的考量因素之一。為了可以更有效的改善高爾夫球頭的擊球
聲音，利用有限元素分析來找出球頭的聲頻分布並進一步找出可以激
發球頭音效的特定頻率。本文利用電腦輔助分析軟體ANSYS 進行分
析，首先對欲分析之球頭模型進行振動模態分析以求出球頭與各部位
之振動模態以及共振頻率，之後以聲學暫態分析以求出球頭所受衝擊
時的聲壓以及聲壓位準分布。最後以聲學暫態分析所得到的結果利用
快速傅立葉轉換以求得聲壓和聲壓位準與頻率的關係並將結果與振
動模態分析所得到的結果做比對。如此在設計一高爾夫球頭時，利用
以上方式去求出一欲設計之球頭模型之聲頻分布，再藉由電腦輔助設
計軟體環境上去做模型的修正以得到舒適度、打擊性能以及打擊音效
兼具的良好球頭。

With the popularity of golfing, the marketing of golf clubs has been
promoted in recent years. The purpose of this study is to investigate the
sound effects of golf impact on different shapes and thicknesses of
striking face of the golf club using the finite element method. The
researcher found that the vibration model and the resonance frequency of
golf club heads. In addition, the researcher used vibration modal
analysis to generalize the golf head modes with the distribution of the
sound pressure. He also used acoustic transient analysis to check the
sound pressure level. Finally, the correlations among the sound pressure,
sound pressure level and sound frequency of the golf club head impacts
were administered. After all, the study findings provides golf head
designers and producers with a reference for designing, revising and
producing comfortable and qualified impact sounds of golf club heads.
