Abstract

In this paper, a path generation problem has been solved by carrying out approximate dimensional synthesis of six-bar, single degree of freedom Watt-II mechanism. The mechanism consisting of all revolute pairs is capable to trace the prescribed trajectory which comprises of twenty four precision points. The dimensional synthesis is carried out using analytical complex number method wherein, the standard dyad/triad and loop closure equations are generated. The final lengths and orientations of various links of the mechanism are determined by solving these equations using a MATLAB code for twenty four coupler displacement positions. The dimensional synthesis of the mechanism is demonstrated and verified on a numerical example.
