A Study of the Solvability of the Position Problem for Multi-Circuit Mechanisms by Way of Example of the Double Butterfly Linkage

Abstract

It is frequently forgotten that the common methods of position analysis of planar linkages, which are based on dyadic decomposition, are not general. This is true regardless of whether a graphical or analytical approach is used. It is demonstrated in this paper that relatively simple linkages can give rise to problems that cannot be addressed by dyadic decomposition methods, and that solution of these problems can be far more complex.
