Dennis Tazir provides an overview of gear excitation caused by the meshing of cylindrical gears and shows how the FVA-Workbench can be used to reduce noise.

• Basics of gearing excitation (contact ratios, stiffnesses, transmission errors)

• Potential for improvement through micromodifications (e.g. crowning, pitch modification, head return and preload)

• Eigenvalue analysis (Campbell diagram)
