| 中文摘要 | 本文是利用個人電腦配合介面卡,以機電整合技術,整合高精度的雷射測距儀、力規(load cell)與平移軸及旋轉軸,發展出高爾夫球桿彎曲剛性與直徑掃瞄系統。彎曲剛性量測方法是將球桿的粗端(butt)固定,並於細端(tip)施以一固定力,造成懸臂樑的效果,以非接觸是雷射自動及快速掃瞄高爾夫球桿的撓度,利用有限差分法計算出撓度的斜率分佈,並以五次多項式近似斜率分佈曲線,再求出斜率分佈曲線導數,以計算出連續的彎曲剛性分佈。測距儀同時可掃瞄球桿直徑,可適用於任何材質的高爾夫球桿量測。最後對一碳纖維高爾夫球桿進行直徑及彎曲剛性量測測試,說明量測系統的可行性。 |
| 英文摘要 | Using the PC based control and mechatronics technology, the high precision laser sensor, load cell, linear and rotation actuator are integrated to develop a scanning system to measure the flexural rigidity and diameter of golf club shaft in this paper. The method and apparatus for measuring the flexural rigidity distribution is fixing the butt end of golf club shaft as a cantilever beam, and deflecting the golf club by applying a fixed displacement on the side of tip end. The deflection curve of golf club shaft is quickly scanning by the laser displacement meter. The slop distribution of deflection is then calculated by finite difference method from deflection curve and approximated by a fifth order polynomial. The flexural rigidity curve is calculated from th4e polynomial of slop. The laser displacement meter is also scanned the diameter distribution of golf club shaft of any materials. Finally, a carbon fiber of golf club shaft is selected as an example to verify the feasibility of the system. |
