Abstract :
A powerful optimization method is proposed in this study for the minimal dimensional designproblem of gearbox. It is a general model that is suitable to use for any series of gear drives systemand can extract both dimensional and layout of components-limited optimization design together.The objective function in this study has many local extremes so for avoiding this situation, variousconstraints have been determined Then, Particle swarm optimization algorithm has beenimplemented to speed up the convergence of optimization and elitist particles searched in problemspace to find optimum value of goal function until all of them converge to the similar set of values.At the end, Results have been presented in the utilitarian diagrams to obtain optimal parametersfrom useful diagrams. The results display that the proposed method in this study is better than otherreported in last works and it shows optimum volume of gearbox being related to a decrease of notjust space but costs, material used to make gearbox component, etc.
