Kinematic Synthesis of Variable Crank-rocker and Drag linkage planar type Five-Bar Mechanisms with Transmission Angle Control

Analytical method to synthesize a variable crank-rocker and drag-linkage planar type planar five-bar mechanism with transmission angle control is designed. The method is useful to reduce the solution space and thus the number of trials and the time required for synthesis. In this paper the synthesis of fivebar mechanism motion, for two separated positions are considered. The portion of the fivebar linkage in Phase-I and in Phase-II is assumed to be a crank rocker type four-bar mechanism and the portion of the five-bar linkage in Phase-III and in Phase-IV is assumed to be a Drag-Linkage type four-bar mechanism.
