When performing a noise, vibration, and harshness (NVH) analysis of a transmission system, the elasticity of the gear mesh plays a crucial role in obtaining useful results. To help you create an accurate gear simulation, new features and functionality in the COMSOL Multiphysics® software enable you to evaluate gear mesh stiffness. Today, we’ll explain why it’s important to account for gear mesh elasticity as well as how to compute and include gear mesh stiffness in your multibody dynamics model.
