Optimal Design Method of Gear Molding

Gears are fundamental machine elements that are widely used in most types of machinery to transmit power and/or motion from one shaft to another at a constant angular velocity. They are used in many fields and under a wide range of conditions, from watches and instruments to the heaviest and most powerful machinery. A peculiar aspect of the considered optimization problem is the presence of many design constraints. To solve this special problem the original design variable domain has been modified according to the constraints prior to the global approximation step, to find the actual feasible design variable domain.
