Unified synthesis of Watt-I six-link mechanisms using evolutionary optimization
Gunesh R. Gogate,Sanjay B. Matekar 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.8
A Watt-I mechanism can operate in eight different combinations of assembly modes and output link. In this paper, a novel approach ispresented for carrying out unified optimum synthesis of various combination types of Watt-I mechanism, irrespective of whether identicalor different ranges of variables are specified for different combination types. By carrying out unified synthesis the less suited combinationtypes can be identified, leading to their elimination from the synthesis process. This results in a saving of the overall computationaltime. The presented approach can be implemented with most of the evolutionary optimization methods. In this paper, the DifferentialEvolution algorithm is chosen as the optimization method. Unified optimization results are presented for two problems. The proposedapproach is general and can be used, with suitable modifications, to carry out unified optimum design of alternate mechanical systemswhich can perform a given task.
