Dimensional synthesis of adjustable path generation linkages using the optimal slider adjustment

A desired continuous path can be generated precisely by an adjustable four-bar linkage. In this paper, a slider is used to adjust the pivot location of the driven side link. The linkage feasibility conditions and path generation flexibilities are analyzed. The synthesis model is established based on the optimal adjustment of the slider location. The global optimal solution is searched by genetic algorithm. The effectiveness of the synthesis approach proposed in the paper is verified by two demonstrated examples.
