In several gear dynamic models the internal excitation due to time variation of mesh stiffness has been considered as a harmonic displacement function at the mesh point. In this study the effects of considering higher harmonic terms of the internal displacement excitation expressed in Fourier series, on the dynamic factors are studied. The finite element model developed for dynamic analysis of geared rotors is modified so that the loaded static transmission error function representing the excitation effect of time varying mesh stiffness can be expressed as a periodic function. The inaccuracies in the dynamic load predictions due to using only a single harmonic displacement function for internal excitation are demonstrated by some numerical examples, and the results of this study are compared with those of recently developed nonlinear models. For numerical examples two different gear-shaft systems are used.
