Theoretical analysis of nonlinear vibration characteristics of gear pair with shafts
Theoretical and Applied Mechanics Letters, 2022 The circumferential vibration of a gear pair is a parametric excitation caused by nonlinear tooth stiffness, which fluctuates with meshing. In addition, the vibration characteristics of the gear pair become complicated owing to the tooth profile error ...
