Design and Analysis of a Cabinet Door Lifting Mechanism
摘要
本論文提出一種新型櫥櫃門升降機構之設計，其主要設計概念與凸輪滾子機構相關。首先根據所搜尋到之現有設計的設計特徵，應用運動合成理論以合成出新型櫥櫃門升降機構之構造。其升降機構中之凸輪外形，為所需驅動的扭力下所對應的凸輪變形結果，可藉由凸輪輪廓合成理論計算得到。接著針對所提出之新型升降機構，利用運動分析方法以分析其運動特性，所分析之結果，再經由驗證確保其理論計算之正確性。之後應用最佳化設計方法求出較佳之設計參數，以改良所提出之新型升降機構的性能。同時，為方便調整機構尺寸並快速建立模型，發展一套參數化設計程式用以繪製所提出之新型櫥櫃門升降機構。最後根據此程式所建立之升降機構模型，進行零件與組合件之初型製作，此初型符合設計特徵並達到所需之升降運動。

This thesis proposes a new design of cabinet door lifting mechanism and the main concern is the cam-follower mechanism. According to the existing designs surveyed for analyzing the design characteristics, the configuration of a new lifting mechanism is synthesized by kinematic synthesis theorem. The cam shape can be determined by the cam profile synthesis approach, and the kinematic analysis is employed to analyze the kinematic characteristics of the proposed lifting mechanism. The analysis results are verified to ensure the correctness of theoretical calculations. In order to improve the performances of the proposed new lifting mechanism, the optimum design method is applied to obtain a better design parameter set. The parametric design program is also developed for model generation of the lifting mechanism. Finally, the prototype fabrication is manufactured from the generated model. The operation procedure shows that the proposed new lifting mechanism design achieves the desired lifting motion.
