論文名稱:可變軸距輕型載具之研發(Research and Development of a Variable-wheelbase Vehicle)
摘要
本研究係有關可變軸距輕型載具之研發。首先針對各種軸距可調整之載具類型,進行廣泛之論文及專利公報蒐集,並加以整理分類及分析其優缺點,再依據此分析結果,歸納出本創新設計發展的方向,設計出一款以八連桿十接頭單一自由度之多連桿系統,作為車身結構之可變軸距輕型載具。其最主要的功用是能切換載具之幾何結構,並進行斜躺式自行車與旅行式自行車之幾何轉換。
依據機構設計之流程,首先定義出主要的功能需求,並依據主要功能及關鍵尺寸,作為設計可變軸距輕型載具的基礎架構,並設計一組連桿機構來進行結構轉換。本研究以SolidWorks繪製可變軸距輕型載具之3D模型,並使用COSMOSMotion進行運動模擬及干涉檢查,最後使用ANSYS Workbench軟體進行應力分析,以確認強度與安全度無虞,並於最後進行實體原型之製作。

ABSTRACT
This thesis deals with the research and development of a variable-wheelbase vehicle. In the beginning, all relevant patents and literatures were collected, classified, and analyzed on the topic of variable frame vehicle. According to the results of patent analysis, a new vehicle was created with single degree of freedom a Mechanism body system By 8 joints10 linkage, which possesses the functions of variable frame turns Recumbent to Touring bicycle.
Following the procedures of creative mechanism design, the performance requirements were defined and the basic structure of the new vehicle was constructed referring to its functions and key dimensions. A new linkage mechanism was designed to coordinate all required functions after the conceptual design is accomplished. SolidWorks was used to build the three-dimensional model of the new variable-wheelbase vehicle, while COSMOSMotion for motion simulation and interference avoidance. Finally, ANSYS was used to perform stress analysis to verify its stress distribution, and make Prototyping finally.
