彈簧是現今許多機器都會使用到的零組件，它是機構動力的來源，本篇論文將以目前應用於滑蓋手機的M形彈簧為背景，利用電腦計算的模擬方法協助產品開發之研究。由於不同幾何形狀與尺寸將會直接影響彈簧的扭力與使用壽命，因此適當的形狀及材料是設計彈簧時所必須注重的課題，本文將建立一套CAD與CAE的輔助設計方法，將設計概念結合電腦的運用，省去一般傳統打樣及試誤法所造成的成本與資源浪費。
本研究計畫共分三部份進行，第一部份是建構一套電腦輔助分析流程，運用於分析M形彈簧結構設計。第二部份將用Pro/Engineer三維繪圖軟體，設計建立六組M形彈簧立體圖，並運用ANSYS得到相關理論分析值。第三部份將進行六組模型的打樣製造與實驗，並將實驗量測值與模擬理論值比對分析，確立所設計CAE流程的可行性與研究價值。

Spring is a component in many machines and is the source of the power of the mechanism. This thesis uses the computer-aided engineering methods to help the development of the product which is the M-shaped spring of the slider phone. Because the force and fatigue life are directly affected by different shapes and sizes of the spring, so the important issue focuses on the shape and material of the spring. This thesis constructs a design guide which combines CAD and CAE methods. The combination of the design idea and computer can eliminate the waste of cost and resource from the traditional making a mold and trial-and-error method.
This thesis divides into three parts. The first part is to construct a CAE design guide to analyze the M-shaped spring structure. The second part is to draw six groups of three-dimensional M-shaped spring models by the software Pro/Engineer and calculate the relative amounts by the software ANSYS. The third part is to make the six groups of specimens and test to find their forces and fatigue life. Finally, the theoretical analysis is compared with the experimental measuring values for ensuring the feasibility of the CAE design guide.
