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 with gear physical properties and the effect of stiffness variation during a mesh cycle is studied.
