Solution Rectification in Three Position Motion Generation Synthesis

In this paper the theory of solution rectification in motion generation synthesis of four-bar linkages is strengthened by presenting the mapping of the three-circle diagram into the center-point plane. This mapping may be used in conjunction with the corresponding mapping of the Filemon construction to eliminate solutions which must change branch to move through all of the design positions when cranks are generated by selecting their center-points. Earlier versions of the theory required that cranks be generated by selection of their circle-points.
