本論文主要分析高爾夫球揮桿動態行為。文中利用有限元素分析軟體DYNA 分析高爾夫球揮桿行為，重點在於將整個模型置於三維重力場空間分析其桿身硬度，桿頭重量所造成之速度、角度、應力等因子之變化。文中利用驅策力矩的方式，來提供揮桿之動力源，藉由兩個旋轉機構來模擬人類揮桿動作，最後將力矩傳至以彈性體建構而成之球桿，達成揮桿模型之建立。文中結果得知，動態響應以及桿身硬度對於揮桿有著關鍵性影響。藉由此電腦數據模擬，並與其他論文實驗數值比較，了解各個影響因子之間的關係，並且提供可信賴與可靠之電腦模擬數值，作為運動科學之參考。

The thesis aims to investigate the golf swing dynamic behaviors by a suitable computer simulation. The FEM analysis software DYNA was used to analyze the golf swing motion. The swing model was made by driving moment at two revolving joints to provide torque of golf swing. The point is to set the model under the three-dimension gravity field to analyze the influences of club head speed, loft angle, lie angle and stresses in the shaft caused by different shaft flexes and club head weights. Form the finding of the study, the dynamic response and the shaft flex play important parts in swing motion. Comparing the results of the experiments of other research, the relationship among swing motion factors and their dynamic responses were conducted. It is believed that this thesis will provide some reliable computer stimulation data for the reference in sport science.
