Gears have an important role in the mechanical and acoustic performances of the systems they are part of. Understanding gear behavior is essential for optimal design and use.


Understand the basics of how gear systems work
Understand the forces, mechanical & dynamic phenomena involved
Understand the phenomena involved in the production of gear noise
Define an experimental & numerical approach to understand a gear system’s vibratory behavior

Participant profile
NVH technicians & engineers wishing to apply their know-how to gear systems

Basic knowledge of structural acoustic radiation
Basic knowledge of structural dynamics

Characterization of a gear mesh (macro- & microscopic scales, kinematics)
Static transmission error calculation (definition, procedure, mesh stiffness)
Demonstrations & exercises using VibraGear software
Dynamic response of gear systems (whining, computation, result analysis, noise reduction)
Optimization of tooth corrections (structuring data, optimization method, solidity study)
Non-linear dynamics (contact loss, clicking, grilling)
