Recent advances in the speed and memory capacity of currentcomputers combined with H-adaptive finite element theory permit thedevelopment of more realistic finite element gear strength models.The speed and memory improvements allow for increased numbers ofelements and degrees of freedom and the addition of more detailedbase regions underneath the gear teeth of the finite element model.The H-adaptive theory increases the accuracy of the finite elementmodel by optimizing the size and shape of individual elementswithin the model. This paper presents results comparing thepredicted fillet strain output of a three-dimensional gear toothmodel with recently obtained experimental strain gage data.Comparisons are made for both spiral bevel and hypoid gears.Preliminary results show excellent agreement between theory andexperiment with peak strain amplitudes agreeing to within tenpercent or less. The inclusion of more accurate base regionsunderneath the gear teeth correctly predicts the range of strainfrom tensile to compressive values as the gear teeth roll throughmesh.
