Connectors play an important role as a bridge in electronic products. Connectors are consisted of several terminal contact springs. After connecting, contact springs will deform and normal force will be generated. Furthermore, normal force affects how connectors send electronic signal. As a result, designing a high quality contact spring is a significant lesson. In this thesis, mechanical properties of common materials of connectors are established and the friction coefficient of different surface coating materials are obtained by experiment. Trough finite elements analysis, the overall analysis of connectors is established. The effect of mechanical properties of various materials can be investigated in the performance of contact springs. Finally, by comparison with computer analysis and experiments, accurate simulation can be achieved. In order to learn how’s the interaction between the characteristics of contact resistance and normal force, which affect the performance of connectors, associated research and papers are collected. Moreover, the experiment is established to investigate the relationship of various type of contact behaviors and the normal force. Therefore, through previous experimental data, the properties of contact resistance can be discussed. Design of Experiment (DOE) is a common analysis method which is applied in the thesis to analyze the effects of the structure of the springs. By establishing the analysis modality, the key parameters of designing terminal springs can be obtained. Optimal analysis is utilized to complete structure of springs. Consequently, the result of optimal analysis matches the contact resistance’s least normal force requests. The analysis procedures in the research will aim the industry as reference of design.目錄..............................I 圖目錄...........................IV 表目錄..........................VIII 第一章 緒論......................1 1.1 研究背景與目的..............1 1.2 研究方法與步驟..............3 1.3 文獻蒐集與歸納..............6 1.4 論文總覽...................9 第二章 連接器介紹.................10 2.1 連接器功能.................10 2.2 連接器結構.................12 第三章 連接器端子CAE模擬分析模式建立..18 3.1 有限元素分析軟體ABAQUS簡介....18 3.2 材料機械性質試驗.............20 3.3 連接器端子公母端子配合模擬建立..25 3.4 連接器模擬之簡化.............37 3.5 模擬分析驗證................44 第四章 接觸型態探討................51 4.1 接觸電阻理論................51 4.2 接觸電阻實驗................56 4.3 實驗結果探討................65 4.4 實驗問題與改善方法...........68 第五章 連接器材料影響分析...........70 5.1 連接器端子載具介紹...........70 5.2 材料性質對於性能影響之分析.....72 第六章 連接器結構造型最佳化設計......76 6.1 實驗設計法介紹..............76 6.2 分析步驟...................80 6.3 品質指標...................83 6.4 結構造型參數水準設計及直交表選用87 6.5 直交表分析..................90 6.6 彈片結構最佳化設計...........98 第七章 結論......................103 參考文獻...........................1054426337 bytesapplication/pdf論文公開時間：2016/08/11論文使用權限：同意有償授權(權利金給回饋學校)連接器端子有限元素分析實驗設計法田口法接觸電阻最佳化thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/263169/1/ntu-103-R01522539-1.pdf
