Abstract: This article presents the optimum design of multiple objective for V-belt drive.With the purpose of getting minimum center-to-center distance, force acting on the shafts and number of belts we derive the mathematical model.The method of sum of linear weight is used for the optimum problem of multiple objective.Weighting factors are calculated with the method of variant coefficient of each objective.lt can be used as a reference to the mechanical engineers for V-belt drive design
