摘要:	在動態使用的情況下智慧型手機滑蓋彈簧及連接器端子的機械可靠度是一重要的課題，尤其當組件的複雜度增加及小型化趨勢持續，此問題更顯重要。本文主要探討智慧型手機滑蓋彈簧及連接器端子之結構分析，首先，使用具有高階非線性大變形分析能力的ABAQUS結構分析軟體進行連接器端子的靜態應力分析及滑蓋彈簧之支撐點反力及應力分析，以確定起始滑動手機時滑蓋彈簧會產生一反力，而當滑蓋通過行程中點時彈簧的反力將轉為推力，同時，滑蓋滑動過程中彈簧之最大應力值及其位置將被計算，以確定最大應力不會產生彈簧之損壞。本文進行手機滑蓋彈簧之理論分析，以彎曲樑理論導出最大應力值公式並與有限元素分析結果比較。最後，本文進行滑蓋彈簧之設計變更，以求更合理之應力分布進而延長其使用壽命。 In case of dynamic applications mechanical reliability for slide hinge spring of cellular phone and connector pin is becoming a serious issue as complexity of the devices grows and miniaturization trend continues. In the present paper, the structural analysis for slide-hinge spring of cellular phone and connector pin has been conducted. First, the stress on connector pin and the reaction force on supported pin are analyzed by ABAQUS, which has the capability to solve the nonlinear and large deformation problem, for ensuring to produce a pull force by spring as the slide-hinge moving from the starting point to half point and to produce a push force as the slide-hinge moving from the half point to the end. Consequently, the maximum stress and its location will be predicted to prevent the failure of spring. In the present paper, the theoretical analysis will be conducted to derive the formulation of maximum stress which will be compared to the FEA results. Finally, the re-design of slide-hinge spring will be performed to propose a new spring with lower stress and longer using life.
