摘要
摘要 市面上手機的種類繁多，比較常見的有: 直板手機 (Bar Phone)、掀蓋手機(Folder Phone)、滑蓋手機 (Slide Phone)、旋轉手機 (Rotary Phone)…等等，本文主要是探討滑蓋手機的滑動機構主要元件，滑蓋手機的關鍵性致動零件在於彈簧，滑蓋手機的產品特色與創新性也在於彈簧的設計，設計工程師在設計初期致動彈簧的選擇上除了要避開專利的保護外，須對於產品特色、規格與消費者需求一併納入考量，本文將介紹常見的滑蓋致動彈簧種類，並針對其中一種M型扭簧做結構分析，探討滑蓋手機的致動彈簧結構與壽命。 由於有限元素法的理論基礎已發展多年，因而發展出許多CAE軟體來輔助機構設計，藉由電腦的分析模擬可獲得相關的設計資料，並可以降低產品開發的Trial and Error，但如何讓CAE軟體正確又有效率的來解決設計上遇到的問題，是設計人員所要克服的難題。本論文主要是以有限元素法為理論基礎而開發出的CAE軟體ABAQUS來分析滑蓋手機的致動彈簧的應力分布，再藉由CAE分析的依據建立合適的結構，並搭配實驗方法取得最合適的設計，最終達成最佳化滑蓋手機設計。

Abstract There are a variety of form factors in the mobile phone market. The most common ones are bar phones, flip phones and slide phones. The purpose of this thesis is to examine the mechanism of the slide phones. The key actuation component in a slide phone is the spring actuator and the characteristic and the innovation of the phone is dependent on the spring’s design. Design engineers have to consider a number of things during the design phases of springs for the slide phones. These include: possible patent infringements, and specifications of the phone, and consumer feedback. This thesis will briefly cover the different spring actuators used in slide phones and focus more in-depth on the M-Spring. It will also cover the structure and life of a spring actuator inside slide phones. Since the theory of Finite Element Method has been around for many years, a number of CAE software has been developed for the purpose of design engineering. The design data can be obtained through computational analysis and simulation, reducing the need for trial-and-error. The big challenge for the design engineer, however, is solving design issues accurately and effectively. This thesis utilizes the F.E.M. based CAE software ABAQUS to analyze the actuation spring of slide phone.
