球道木桿不均厚桿面設計對特徵時間表現之分析

背景：影響桿頭擊球表現的主要因素為合金材料與彈簧效益，以設計新桿面結構，創造最佳擊球手感與更遠距離之球道木桿。目的：透過鐵系材料熱處理與CNC 加工製程製作的球道木桿桿面，創新開發具高彈簧效益(特徵時間)之桿頭。方法：使用455 不銹鋼為材料，經過熱處理與時效處理後，進行顯微結構、機械性質分析。透過CNC 加工處理，設計7種不同桿面背部花紋的球頭，每種3顆，共計21 顆。再將完成品以實務量測方法進行特徵時間(Characteristic Time, CT)、耐擊程度等表現。以三因子變異數與LSD 事後比較進行分析。結果：455 不銹鋼在S850℃-A550℃熱處理後，其機械性質具高強度與較佳延展性，適合發展高彈簧效益的桿面。特徵時間(CT)值上之研磨前、後三因子間 (花紋*厚度*位置) 交互作用未達顯著水準。經二因子比較花紋與位置、厚度與位置在研磨前、後達顯著差異。耐擊測試經45m/s 的撞擊檢測後皆可達規則限定標準以上。結論：455 不銹鋼經不均厚桿面設計其彈簧效益可達高特徵時間表現。桿面厚度越薄其特徵時間表現越高，但背面花紋設計對其影響不大。

Background: The main factors to influence on the stroking performance of club head are alloy and spring-like effect. Design the structure of new club face to create the fairway wood which can show best stroking feeling and let driving distance become longer. Purpose: The club face of fairway wood is processed through the iron alloy heating procedure and CNC to innovate the club head with high spring-like effect (characteristic time). Method: Use 455 stainless steel processed by heating and aging treatment, to do the analysis on microstructure and mechanical properties. Through CNC to design seven different patterns for the back of club face, each pattern for three club head. The total amount is twenty-one. Make finished product be test the characteristic time and the ability of strike by the practical measurement. To analyze after the compare between three-way ANOVA and LSD. Results: After 455 stainless steel was heated in procedure S850℃-A550℃, mechanical properties became superior and had the better malleability, it is suitable for developing the club face of high spring-like effect. Before and after grinding among three-way ANOVA (pattern*thickness*place), did not achieve the significant level on the figure of characteristic time. Through two-way ANOVA (pattern*place and thickness*place), showed the significant deviation before and after grinding. After doing the crash test by 45m/s, all the results can reach the higher limited standard. Summary: 455 stainless steel was designed with the different club face's thicknesses of fairway wood can make spring-like effect achieve high characteristic time.The much thinner club face let the characteristic time perform highly. But there was no obvious effects from the patterns of the back club face.
