Dyad Synthesis of Planar Seven Bar Mechanism with Variable Topology for Function Generation

G.M.Gadad and Srinivas Balli

ABSTRACT: Planar linkages may be thought of as combinations of vec-tor pairs called dyads. Amongst the different methods for synthesizing planar mechanisms one of the methods is the dyad synthesis and has been applied to five-bar and seven- link variable topology mechanisms [VTM]. This paper attempts to synthesize Seven-link mechanism with variable topology for function generation of two finitely separated positions. An analytical method of dimensional synthesis is performed upon the envisaged mechanism by designat-ing the equality constraints, assigning the variable types and then identifying the specified design space to deter-mine the solution.
