Abstract
Beats frequency due to the modulation of vibration can occur when machines with similar oscillations are mounted on the same base or when rotating shafts with close speeds share the same bearings. In these mechanical systems, forces interference from each source of vibration occur and a conventional data acquisition process for vibration analysis and dynamic balancing does not present satisfactory results. In this paper we present a simplified procedure to perform vibration analysis and dynamic balancing in systems subjected to beats frequency. This procedure is based on adjusting the data acquisition configuration parameters using conventional hardware and proprietary software. The results obtained show that the procedure presented in this paper has good efficiency. In addition, it is possible to notice significant benefits in terms of cost, simplicity and speed, especially when comparing with other types of more complex approaches that are being used today to treat similar problems.
