Developing of model for vibroacoustic signals of roller bearing

[摘要] At present, the automated systems for vibroacoustic diagnostics (ASVD) are being used more widely. They are intended to rapidly assess the technical condition of the machinery as such and its particular mechanisms. The ASVD's assembled according to a modular principle consists of sub-systems for collecting and switching information on the vibration state of an object, primary analog processing subsystems, and secondary digital processing and control. The current state of microprocessor technology makes it possible to create small-size ASVD's capable of not just making a decision on the operability of a diagnosed node, but also recognizing the type of the defect and the degree of its danger to the mechanism.
