 Title: 負波桑比機構之設計與分析;The design and analysis method of the mechanism by using the theorem of negative Poisson's ratio Authors: 陳耀庭;Yaw-Tyng Chen Contributors: 機械工程研究所 Keywords: 負波桑比;內凹型泡棉;機構;negative Poisson's ratio;re-entrant foams;mechanism Date: 2002-06-21 Issue Date: 2009-09-21 11:38:36 (UTC+8) Publisher: 國立中央大學圖書館 Abstract: 本文主要以具負波桑比的傳統內凹型蜂巢結構，設計出具負波桑比性質之三維機構，並且對此機構作波桑比值以及體積膨脹倍數的曲線分析，試著就各種不同的桿件比例參數進行探討。首先我們對機構進行幾何關係之數學式推導及計算出負波桑比理論值，其次利用ADAMS機構模擬分析軟體，模擬不同桿件參數並計算其體積膨脹倍數。 本文除了探討桿件間夾角（θ）、及不同桿件長度比(α)等參數對機構波桑比與體積膨脹倍數之影響，更試著對原始機構稍作改變，設計出 “等體積收放比例輪椅”以及介紹“組合式伸縮空中鷹架(空中吊架)”兩種機構之組成方式與未來發展方向，以期達到將負波桑比性質實際應用的目標。 The design and analysis method of the mechanism by using the theorem of negative Poisson's ratio Appears in Collections: [Graduate Institute of Mechanical Engineering] Electronic Thesis & Dissertation
