Abstract

The Gear Whine Noise (GWN), as well as the gear rattle noise, is one of the main vibro-acoustic phenomena of gearbox. For that reason GWN is an important problem to solve or to reduce or to "manage" at least in an appropriate way. Running conditions of the gear-box were reproduced by means of an innovative test-bed, which allows to perform the test without using the engine. This means that the noise and vibration due to the engine were not introduced into the system. From this point of view we say that the present study was performed in optical Noise, Vibration and Harshness.
