Revisiting Planar Four-Bar Precision Synthesis with Finite and Multiply-Separated Positions

Abstract

This work revisits the topic of planar four-bar precision synthesis to approximate prescribed coupler positions and velocities-a topic originally published by Schaefer and Kramer ⁽¹⁾. Here, more general equation systems are formulated that include crank and follower dyad vector loop equations as objective functions, derivatives of these equations as velocity constraints and inequality constraints for order defect elimination.
