摘要

羽毛球是世界性的體育運動，每一顆羽毛球是由16根鵝或鴨的羽毛及軟木球頭所製成，球體中羽毛的毛葉和毛梗為最脆弱而易損壞的部位，而且任何一根羽毛的損壞就會使整顆球失去原有飛行屬性。近年來，全球的羽毛球運動人口持續增加，但是原料羽毛的供應卻無法跟上，導致羽毛球的價錢持續上揚。因此以人造羽毛替代真實羽毛的構想愈來愈具備商業價值。
本研究主要目的分為二部份。一為仿真羽毛之外表型態設計:使用Nikon攝影機擷取真實羽毛之數位圖像，藉由影像處理技術將真實羽毛外型圖像經由傅立葉轉換、二值化運算、型態分析等程序，以突顯出真實羽毛之輪廓圖像，並將處理後圖像匯入建模軟體以設計仿真羽毛的初始模型。其次是真實羽毛機械屬性實驗擷取:使用動態實驗與靜態實驗，並以實驗設計分析羽毛於彎曲度、正向拱度、負向拱度之機械屬性，從而建立仿真羽毛的仿真屬性條件。
本研究主要成果，包括:1.運用影像處理設計三套羽毛梗的初始模型開發。2.依據真實羽毛靜態與動態之機械屬性的最佳線性回歸方程式，建立有效信賴區間，以便未來仿真羽毛開發，能精準掌控羽毛外型與屬性。

Badminton is a sport of the world. A Shuttlecock is made from the 16 goose or duck feathers and a cork ball head, Feather leaves and stems are most vulnerable to damage. Any damage in these areas cause the ball to lose the original flight properties. Recent years, playing populations badminton continue to grow around the world. However, the supply of raw material feathers can’t keep up, leading to the price rise of badminton. The idea of artificial feathers in replacing real feathers has commercial values and draws attentions of global research.

The objectives of this study are two-fold. 1. Emulation of a feather appearance patterns design: Using Nikon cameras to capture real feathers, and applying image processing technology via a Fourier transformation, binary arithmetic, and pattern analysis program to improve image of the feathers. 2. Feather mechanical properties experiment retrieval: Using dynamic experimental and static experimental design to analyze feathers in curve, tune positive arch, negative arch with respective to different loads, and these establish conditions for emulation feathers simulation attribute.

The outputs of this study including three sets of feathers Terrier initial models and static and dynamic mechanical properties of the best linear regression equations retrieved from real feathers. Confidence intervals of these regression equations are built, that can be used developing artificial feathers.
