Paper Abstract

A major problem in directly measuring synchronous belt noise is that, often, the noise coming from bearings, fans or any type of vibration transmitted through the belt drive may be taken for belt noise. In the automotive field, most of the times, the noise generated by belt drives is estimated using microphones in the proximity of belt, crankshafts, idlers...Such a method can be misleading, since it may easily include the contribution of background noise at some frequency. Moreover, a big amount of data is needed to test different layouts and running conditions. This work aims at developing a tool for estimating the acoustic radiation of synchronous belts during the design stage, one of the main objects being that of reducing the high number of tests currently employed.
