高爾夫球桿頭力學及音響

本文目的在利用擊球音響，建立打擊聲音好聽之桿頭設計準則。試驗方法是以動態信號量測得到高爾夫桿擊球的聲音，根據人耳聽覺判斷打擊聲音品質以建立高爾夫打擊聲的頻譜特性品質，以建立桿頭好聽與否的鑑別方法。同時探討桿頭結構動態設計，利用有限元素法分析桿頭的結構與音響頻譜特徵之關係。並使用線性回歸或類神經網路，提出桿頭反彈係數的鑑別法。由共振頻率及質量得知桿頭反彈係數是否符合規定。

This study is to establish a design criterion golf head based on sound quality during striking a golf ball. The experiment method is to measure sound during striking a golf ball by using dynamic signals analyzer to get its frequency spectrum plots. The sound quality is determined by human hearing and identification can be established due to the characteristics of the frequency spectrum of striking sound. The finite element method is also use in the design of golf head. Sound characteristics described by frequency spectrum and structure dynamics of golf head. The linear regression method or the neural network method is applied to suggest the identification method of the coefficient of restitution. By the resonance frequency and mass will know if the coefficient of restitution conform to the regulations.
