本文提出一個動作即可完成擴大或縮回,而且長寬能同時一起變化之伸縮矩形桌的機構設計,此機構可讓使用者由矩形桌任意一邊施力即可改變桌面面積大小。 本研究利用機構創造設計程序之方法,依照設計需求與設計限制,設計出各層桌板之間的連動機構。此伸縮矩形桌的3D模型是藉由電腦輔助設計軟體Solidworks進行建構,並利用內建的干涉檢查功能,確認設計無干涉情形產生;再利用電腦輔助分析軟體ADAMS進行動態模擬分析、機構之機械利益分析與機構的尺寸最佳化,檢測整體的機構是否為一省力的機構,可讓使用者輕鬆操作;再應用Solidworks軟體進行應力及位移分析,以確定所設計機構之強度,最後則進行實體模型之製作,驗證設計出的伸縮矩形桌的正確性與可行性。
This thesis presents an innovative mechanism design for retractable rectangular table which needs only one-input action to transform. This mechanism design could allow the user to apply the required force at any point along the edge of the rectangular table to change the area of tabletop. This research applies the creative mechanism design method. The required link-mechanisms of table plates are created and designed in according to the design requirements and constraints. This retractable rectangular table’s 3D model is built through Solidworks software and uses the built-in interference check function to confirm its design without generating interference. Then, the dynamic simulation, the mechanical advantage and the optimized dimensions of this design have been investigated via ADAMS software to check whether the whole design is effort-saving and easy to operate or not. Then, the strength analysis is done by using Solidworks software to verify the strength of this design. Finally, a prototype of this retractable rectangular table has been fabricated to confirm its feasibility.
