Variable topology mechanisms with obey characteristic of compatibility are enumerated. According to characteristic of compatibility, activity of joint in mechanism can be confirmed. First, make a judgment from motion requirement of functioning links whether the mechanism should be design as a variable topology mechanism . According to operation space of functioning links, the joint type and orientation of joint between ground link and input link or output link can be presume. And then we can confirm the smallest operation space of loop in mechanism by joint compatibility, confirm the joint type and orientation of common joint in every loop by loop compatibility, and construct the structure of mechanism by mobility compatibility. By the way of compare the difference of topology between different stage, the position of variable joint can be arrange. Finally, label all joint on the satisfaction of joint compatibility. Utilize the methodology of synthesizing variable topology mechanisms, and take the latch mechanism as an example. Since the admissible latch mechanisms conforms the characteristics of compatibility, it could avoid result that mechanism can’t satisfy the purpose by the unanticipated constrained of joints. And through the arrangement of position and number of variable joint, it can synthesis the ideal mechanism efficiently.710136 bytesapplication/pdfen-US可變拓樸機構拓樸合成可變接頭相容性閂鎖機構variable topology mechanismtopological synthesisvariable jointcompatibilitylatch mechanismthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/255876/1/ntu-100-R98522641-1.pdf
