Study of the Influences of Transient Crack Propagation in a Pinion on Time-Varying Mesh Stiffness [PDF]
Shock and Vibration, 2016 Cracks in a cracked gear may further propagate by a tiny length in a very short time for several reasons, such as material fatigue and load fluctuations. In this paper, this dynamic process is defined as transient propagation of cracks.

Dynamic Analysis of Gear Systems with Dynamic Mesh Stiffness and Time- Varying Bearing Stiffness
Nonlinear DynamicsAbstract In this study, a novel analytical model for dynamic mesh stiffness of spur gears is developed using variable cross-section beam theory, explicitly accounting for driving speed effects. The dynamic mesh stiffness is determined by applying the modal superposition method to analytical model equations, and subsequently validated using both

Transport, 2022 Rail corrugation is usually generated in modern railway transportations, such as high-speed railway, urban railway, and heavy-haul railway. It is one of the major excitations to the wheel–rail dynamic interaction, which will cause extra vibration and noise, failures, or even risk of derailment to the vehicle and its components.
