Dynamics of Helical Gears

Application ID: 36301

This model illustrates the dynamics of helical gears. It is built using the gears functionality in the Multibody Dynamics interface in COMSOL Multiphysics.

A transient study is performed to analyze the effect of constant gear mesh stiffness, varying gear mesh stiffness, and the transmission error on the angular velocity of driven gear and the contact force. An eigenfrequency analysis is performed to compute the natural frequencies and mode shapes of the gear pair for rigid and for elastic gear mesh.
