Abstract
In the present paper two different approaches for spurgear noise reduction using micro-geometrical modifi-cations are compared. The two approaches are basedrespectively on the reduction of Static TransmissionError (STE) and Dynamic Transmission Error (DTE)fluctuations. The dynamic behaviour of the system iscomputed through a simple lumped parameter model.A genetic algorithm is proposed to find the best solu-tions inside the parameters space because the evalua-tion of the objective functions requires finite elementscalculations and numerical ODE integrations. A relia-bility analysis is afterwards performed to evaluate theeffect of manufacturing errors on the dynamic perfor-mance of the achieved optimum.
