摘要

本文旨在採用一套網際程式框架建立模組化平台系統，使平台擁有高擴展性、靈活性、客製化等好處，並使用一套機構尺寸合成模組和一套機構動態模擬模組，進行機構尺寸合成和 3D 動態模擬。使用者可透過瀏覽器連接至程式框架中，依據設計需求輸入機構運動簡圖與設計參數，並採用實數基因演算法或差分演化演算法進行後端運算處理。為了能讓使用者檢視合成結果，同時使用 JOGL 開發一套機構動態模擬系統，並且分析了機構干涉問題，以迴避平面連桿機構在空間中生碰撞。其後也為了讓系統合成結果可與其它電腦輔助設計、電腦輔助工程或電腦輔助製造等系統結合，分析完成後可下載所需零件檔案。最後利用文獻中之數個案例進行驗證。

The main purpose of this study is to integrate a web-based framework to establish a modular dimensional synthesis platform with 3D kinematics simulation capabilities to gain the benefits of high scalability and customization. Mechanical designers can use a web browser to log into the proposed system to perform the dimensional synthesis of planar pin-jointed mechanism with designated kinematics pattern and design inputs.

In this system, the real-coded genetic algorithm and differential evolution methods were used to search for the optimal solutions with interference avoidance in the back-end computation. The 3D kinematics simulation of the synthesis results were achieved through the JOGL techniques.

In order to further integrate the synthesized results with other computer aided engineering and manufacturing systems. After each synthesis, users can download the system-generated CAD parts according to the synthesized dimensions through the web-based interfaces. To the end of this thesis, the existing path generation mechanism test cases are used to verify the effectiveness of the accomplished system with good accuracy.
