Accurate prediction for mechanisms’ dynamic responses has always been a challenging task for designers. For modeling easiness purposes, mechanisms’ synthesis and optimization have been mostly limited to rigid systems, making consequently the designer unable to vow that the manufactured mechanism satisfies the target responses. To address this limitation, flexible mechanism synthesis is aimed in this work. Two benchmark mechanisms being the core of myriad mechanical devices are of scope, mainly, the flexible slider-crank and the four-bar. In addition to the mechanism dimensions, materials properties have been embedded in the synthesis problem. Two responses are of interest for the slider-crank mechanism, the slider velocity, and the midpoint axial displacement for the flexible connecting rod. Whereas five responses have been compiled for the four-bar mechanism synthesis. A comparative analysis of seven optimization techniques to solve the synthesis problem for both mechanisms has been performed. Subsequently, an executable computer-aided design tool for mechanisms synthesis has been developed under MATLAB®. Numerical outcomes emphasize the limits of a single-response-based synthesis for a flexible mechanism. It has been proven that combining different responses alleviates possible error and fulfill high-accuracy requirement.

Precise and continuous generation of rhombus path by adjustable four-bar mechanism is investigated and confirmed using Reconstructed Adjustable Parameter Curve (RAPC) technique. RAPC method is able to extract adjustable parameter value of intermediary path points along the path generation profile corresponding to uniformly incremented crank angle values. Harmonic Spacing (HS) algorithm is used to improve the precision points spacing along the perimeter of intended rhombus path. Optimal dimensional synthesis of adjustable four-bar mechanism makes use of these precision points. Simulation of motion of adjustable four-bar mechanism to generate profile path of rhombus is carried out to verify the dimensional synthesis of the linkage. Optimization combining Genetic Algorithm (GA) and Pattern Search (PS) is implemented to synthesize rhombus path generating mechanism. Results show the achievement of precise and continuous path generation with high accuracy for the selected rhombus path profile.
