可換向式座椅的創意機構設計

Abstract

應對公共交通日益增長的重要性，本論文提出了多種新型可換向式座椅設計。在19 種可行的設計中，選出了五種進行詳細的尺寸設計、運動與力分析。這些新型機構僅包含旋轉關節，使製造過程更為簡便，與現有設計相比具有明顯優勢。設計過程整合了顏的創意性機構設計[1]，以及Kinzel、Schmiedeler 和Pennock 的幾何約束編程（GCP）[2]。此外，運動分析中採用了牛頓-拉夫森方法[3]和運動係數法[4]。靜力分析和模擬也被用來確定調整座椅方向時的關節力。所有五種設計均保持了可行性，但某些設計顯示出更佳的性能。

In response to the growing importance of public transport, new reversible seat designs have been synthesized. Five of the 19 viable designs were selected for detailed analysis of their dimensions, kinematics, and forces. Unlike current designs, the new mechanism comprises only revolute joints for manufacturing ease. The design process integrates Yan’s creative design of mechanism [1] and Kinzel, Schmiedeler, and Pennock’s geometric constraint programming (GCP) [2]. Furthermore, the Newton-Raphson [3] and kinematic coefficient method [4] is used for kinematic analysis. Static force analysis and simulation were also performed to determine the joint forces when adjusting the seat orientation. All five designs remained viable, but certain chains exhibited better performance.
