Influence of gear topology discontinuities on the nonlinear dynamic response of a gear train subjected to multiharmonic parametric excitation
Résumé
This work investigates the influence of holed gear blanks on the nonlinear dynamic behaviour of a flexible gear train. The system is excited by a multiharmonic internal excitation, namely a time-varying mesh stiffness and the static transmission error. This presentation will summarise the numerical procedure that has been developed to study such systems. A reference configuration without holes is used to give insight into the underlying dynamics and to highlight the effects of holed gear blanks. A thorough parametric study then addresses the robustness of the forced response curves and bifurcation structure to changes in gear blank topology.
