| Summary: | 碩士 === 國立屏東科技大學 === 機械工程系所 === 95 === This work aims to develop the evaluation program and design rules and to establish the standard operational procedure (SOP) for golf club design and manufacturing. Computer Aided Engineering (CAE) technique adopting finite element analysis commercial software will be introduced to perform theoretical analysis for golf clubs. Theoretical modal analysis (TMA) and will be carried out to obtain modal parameters, respectively. Experimental modal analysis (EMA) on a golf club is also conducted to determine modal properties of practical golf club structures. The experimental results can then be used to verify and validate the analytical model. Virtual Testing (VT) combining CAE and EMA can lead to integrated design of golf clubs. The impact of golf club will also be theoretically analyzed and experimentally validated. The effect of structural parameters, such as boundary conditions and material properties, on the golf club performance will be investigated. And, the sound quality of the golf club during swing will be measured and evaluated to define the preferred sound spectrum for golf club design. In summary, the objectives of this work are to establish the performance indices (PIs) for the golf club: (1) vibration-based PI: sweet spot of club head and impact energy of golf club; (2) strength characteristic PI: Stress of club head as well as failure evaluation; (3) sound characteristic PI: preferred sound spectrum and dominant frequency of club design. This work will establish analytical and experimental techniques as well as virtual testing procedure for golf club design. The developed methodology can not only reduce R&D time and cost but also improve the golf club performance and product quality.
