Synthesis of Basic Linkages for Input-Output Coordination

Computer-aided graphical design procedures are introduced for the synthesis of basic linkages. The two-handled block concept is utilized to illustrate the design of four-bar linkages, slider-crank mechanisms, the first inversion of the slider-crank mechanism (FISC), as well their combinations for multi-position input-output coordination. It is shown that the coordination of input-output in the resulting mechanisms is accurate, and that the error is generally less than 3% of the range.
