A Lightweight Model for Gear Mesh Dynamics Incorporating Variable Mesh Stiffness [PDF]
MATEC Web of Conferences, 2015 Variable stiffness of the gear tooth mesh for a pair of spur gears is computed using an accurate lightweight mathematical formulation. This is used to simulate gear dynamic behavior. Gear eigenfrequencies are calculated for the SDOF system and correlated

Improvement on Meshing Stiffness Algorithms of Gear with Peeling [PDF]
Symmetry, 2019 This paper investigates the effect of a gear tooth peeling on meshing stiffness of involute gears. The tooth of the gear wheel is symmetric about the axis, and its symmetry will change after the gear spalling, and its meshing stiffness will also change during the meshing process. On this basis, an analytical model was developed, and based on the energy
