Synthesis of planar mechanisms, four-bar mechanisms, 3 coupler positions generation, nonlinear synthesis equations

Four-bar planar mechanisms have wide applications in industry and thus receive more attention from machinery design researchers. The proposed approach in this paper relies on forming a mathematical model for the mechanism position incorporating the 3 coupler positions. The model consists of 8 nonlinear equations considering the transmission angle of the mechanism in the 3 coupler positions. A case study is presented as a justification for the proposed approach. Exact coupler positions are attained with transmission angles not more than 18 % of the optimum value of 90 degrees.
