Classifying, Predicting, and Reducing Strategies of the Mesh Excitations of Gear Whine Noise: A Survey

Abstract EN

Gear whine noise has attracted increasing attention from researchers in both the academe and the industry over the past two decades.

The wide range of research topics demonstrates that there is a huge technical challenge in understanding the source-path-receiver mechanisms deeply and predicting the gear whine noise precisely.

Thoroughly understanding the sources of gear whine noise is the first step to solving this issue.

In this paper, the authors summarize a certain number of published articles regarding the sources of gear whine noise.

The excitations of gear whine noise are classified into three groups: transmission error along the line of action direction, frictional excitations along the off-line of action direction, and shuttling excitation along the axial direction.

The mechanisms, characteristics, predicting approaches, measuring methods, and decreasing strategies for these excitations are summarized.

Current research characteristics and future research recommendations are presented at the end.
