Analytical Method of Sixth-Order Connecting Coupler-Curve Synthesis of Planar Four-Bar Linkages

This study presents the kinematic synthesis of planar mechanisms using precision point analysis for three, four, and five target positions. The research explores the application of graphical synthesis techniques to design mechanisms that accurately follow prescribed motion paths. Various configurations are examined, comparing their synthesized motion with theoretical precision points to evaluate the accuracy and feasibility of the proposed designs. Additionally, numerical optimization methods are considered to refine the results and improve motion fidelity. The study also extends the discussion to higher-order synthesis, incorporating additional precision points for improved accuracy in motion generation. The graphical results highlight the effectiveness of the synthesis approach, demonstrating its applicability to practical mechanism design. The findings contribute to the understanding of planar mechanism synthesis and provide insights into enhancing design methodologies for motion control applications. This paper presents GIM software, an educational and research software designed to facilitate the kinematic analysis of planar mechanisms. The software was developed to address the challenges students face in understanding kinematic theory and mechanism synthesis, providing an interactive and user-friendly platform for modeling and analyzing n-degree-of-freedom linkages.
