Investigating Epicyclic Gear Whine

Testing epicyclic gear systems leads to discoveries that will help eliminate gear noise during the design phase.

Gear whine is a major source of unwanted noise in automotive applications. It is tonal in nature, which makes it more apparent to the human ear than other stochastic noise mechanisms. Prediction of gear whine behavior in automatic transmissions is a particularly complex problem, where the conventional FEA approach precludes the rapid assessment of “what […]
