Abstract
A design technique for coupler curve generating mechanisms is developed. The procedure is based on a multi-variable search using an objective function developed from topological properties of spatial curves in an arbitrary reference system. The method completely specifies the mechanism and its orientation relative to the chosen co-ordinate system, which generates the best approximation to the desired curve. The procedure always converges from any set of starting conditions. The technique is well suited to digital computer design of planar and spatial mechanisms, as it permits both the synthesis and the kinematic analysis of the mechanism. The 4R and the RGCR four-bar spatial linkages with coupler points are used to illustrate the synthesis procedure.
