摘要

本文主要是針對曲棍球桿進行實驗模態分析及理論有限元素分析，以獲得曲棍球桿之振動特性。首先以有限元素法對有限元素模型進行模態分析，得到理論模態參數，包括自然頻率、模態振型，將理論與實驗之模態參數結果作模型驗證，驗證成功後，可將有限元素模型可視為一等效模型，藉此探討曲棍球桿的振動特性之物理意義。

This text mainly focuses on the vibration characteristic of hockey stick through the method of the EMA (Experimental Model Analysis) and theoretical FEA (finite element analysis). First, the theoretical model parameters, including natural frequency, model shape, will be observed by means of the FEA. Second, the theoretical model verification will be compared with the experimental model parameters. Finally, the certificated finite element model could be treated as an analytical model; The Hockey in three types of boundary conditions, is also analyzed to compare their modal frequencies and mode shapes. Find spring and freedom, fixing the relationship between the boundary. The modal properties of golf club in grips condition can then be predicted.
