Noise and vibration analysis of conveyor belt

Abstract

The article deals with the measurement of conveyor belt noise and vibration. The conveyorbelt was supported on six rollers fixed on three plates of stand, return and drive drum. Thesesix rollers were produced in two sets (convectional tube and accurate tube). Rollers were driven by a rubber belt. The noise was measured and evaluated on both sides of the conveyor. Vibration of the conveyor was measured at four locations of theconveyor construction.All measurements were performed in an unloaded condition. In conclusion of the article is a summary and evaluation of all measurements. The vibration of the conveyor is comparable in both cases,however,the rollers from accuracy tube excite the construction less, and this results in a lower totalnoise. By comparing the acceleration to the dominant frequency, it is obvious that the noise and the vibration of the belt conveyorconstruction were reduced by using rollers from accuracy tube.
