本研究旨在探討如何利用組裝條件的變更來模擬出旋轉滑蓋的組裝公差,並在圖面上呈現出偏擺和間隙現象,使滑蓋設計工程師在設計過程中,能即時的由圖面上看到旋轉滑蓋在組裝後所產生的累積公差。此外,本研究並結合上述方法及田口實驗法來求取旋轉滑蓋組裝公差之敏感度,以達到穩健化公差設計的目的。
本論文的研究內容包括:(1) 針對旋轉滑蓋的機構特性,設定組裝條件及凸輪從動機構,使旋轉滑蓋可以在電腦輔助機構分析下,在圖面上實際呈現出組裝公差,以提供公差模擬的可視化,(2) 找出旋轉滑蓋的組裝尺寸鏈,並將尺寸加以參數化,以利修改圖面參數時,可即時反應組裝公差在圖面上,(3) 以田口法為基礎,旋轉滑蓋的組裝尺寸公差為控制因子,透過設計實驗找出敏感度較大的相關尺寸公差,並將公差進行穩健化設計,以做為旋轉滑蓋在設計階段之公差設計依據。
關鍵字:旋轉滑蓋、組裝公差、田口法、穩健設計
In this thesis, a simulation was developed for the assembly tolerance in a rotational sliding hinge by modifying the assembly constraints. During the design process for a sliding hinge, the effects of deflection and gaps can be illustrated in real time by graphical representation. After assembly, design engineers are able to determine the tolerance stack of the rotational slide hinge. This method was integrated with Taguchi experimental design to determine the sensitivity of the assembly tolerance in order to achieve a design with robust tolerances.
The thesis included the following three topics: (1) Provided a visual representation of the tolerance simulation. Based on the structural properties of the rotational sliding hinge, the assembly conditions and cam-follower connection were configured for the rotational sliding hinge to demonstrate the actual assembly tolerance in a graphical representation through the use of computer-aided mechanism analysis. (2) Determined the dimension chain for the rotational sliding hinge and parameterized the values to reflect the assembly tolerance in real time when changes were made to the design parameters. (3) Based on the Taguchi method, the tolerances for assembly dimensions were used as the control factors. The corresponding dimension tolerance with the largest sensitivity value was determined by experiment. Robust design was performed on the tolerances. This work can be used as a reference for tolerance design when designing a rotational sliding hinge.
