Abstract
A technology is described for revamping vibration analyzers by introducing an additional intelligent unit for analyzing temporal characteristics of measurement signals. The unit flowchart includes a database, storing expert appraisals, and a knowledgebase, constructed based on the method of identification measurements of the regularity/chaoticity properties in the characteristics of vibration signals using the technique of scales. A computer-aided device has been developed for studying the applicability of the proposed techniques. Results of the vibrodiagnostics of a pumpjack with this device are presented.
