Optimum Synthesis of Path Generating Adjustable Mechanisms With Improved Slope Continuity of the Control Parameter

Abstract

Adjustable mechanisms have been studied in literature for path and function generation. In this paper, a path generating four-bar mechanism with an alternate single parameter adjustment is proposed and optimally synthesized, using the method of Differential Evolution. Two new approaches are developed, aimed at improving the slope continuity characteristic of the control parameter. Optimum synthesis results are obtained using the proposed approaches. The results show that the proposed approaches lead to improved slope continuity characteristics of the control parameter.
