| Abstract: | A constrained algorithm model was constructed to formulate the maximization problem on the minimum transmission angle of working stroke for offset crank-slider linkages.An adaptive penalty function technique was presented to efficiently handle its constraints.Consequently,due to its simplicity and efficiency,the particle swarm algorithm was employed in finding the global optimization solution of the model.The proposed approach was tested against a numerical case study and the results were compared extensively with ones obtained by other modes and algorithms to demonstrate its effectiveness and robustness. |
