平面式封閉式多迴路平台機構因具有高負載誤差累積小等之特性,所以
可以滿足精密性要求更高之工作目地.而且若能配合其基底的運動,亦可達
到空間平台機構之部份功能.本研究針對現有龐大數量之三自由度八連桿
平台機構之拓樸圖集,提出選取拓樸圖之規則,並進行實際機構之轉換,再
對所轉換之機構加以逆向運動分析,及其在工作空間之分析,以及臨界位置
之探討 . 本研究所得之數據資料,可做為設計平台機構之參考

The study is aimed to the design and analysis of the planar
mechanismwith 3 d.o.f and 8 links . Firstly the rules of
selection for the graph are developed , and the proper graphs
among many possible graphsare specified . The schematic diagram
of these mechanisms are also presented . Then the motionanalysis
and inversed motion analysis of the platform mechanisms are
derived .Lastly the workspace and singular position of the
platform mechanism are discussed and some criteria are proposed
. The findings in this study should be useful for the
application of the planar platform mechanism
