中文摘要 | 本文利用解析法來合成平面瓦特Ⅰ型剛體導引機構通過五個精確位置。首先利用 複數與雙接頭桿對之觀念,來建立此型機構之剛體導引的數學模式;進而推導此型機構通過 四和五個精確位置之運動解析方程式;再根據此解析方程式來合成通過四和五個精確位置之 瓦特Ⅰ型剛體導引機構;最後,提出兩個設計實例供作參考。本文之結果可提供平面剛體導 引機構設計之另一種選擇,且比一般四桿機構具有更多的設計變數,以滿足一些特定的設計 需求,如桿長比與傳動角等;亦可作為合成此型機構通過更多數精確位置之起始猜測值之用 。 |
英文摘要 | This paper applies an analytical method for dimensional synthesis of Watt-I linkages which guide the coupler to pass through five prescribed precision positions. Complex numbers and the concept of dyad are used to establish design equations. With the aid of compatibility equations, the nonlinear design equations are solved by an analytical method. Then, Watt-I linkages passing through four and five precision positions are synthesized. Two design examples are presented. The results of this work provide an alternative selection for rigid body guidance because Watt-I linkage has more design parameters than four-bar linkage for specifying more constraints, e.g., link-length ratio and transmission angle. Besides, the synthesized linkage can also serve as the initial value for optimal synthesis of a Watt-I motion generator with more precision positions. |
