Dynamic simulation of mechanical fault transition

摘要

Over the past few decades many vibration and signal analysis techniques have been investigated, developed, and used to provide operational response information about mechanical power transmission systems for monitoring and diagnosis of components and their worn/faulted condition. The presence of multiple sources of excitation and forcing in a complex distributed mechanical structure (rotor transmission shafting, gearing, bearings, casing, and foundation) presents problems for algorithms that are designed to present a single feature asosciated with a single fault mechanism. The consequence of the mecahnical structures dynamic interaction is not alwasy clear but an understanding of it is critical for the successful developmnet of effective integral signal processing algorithms and automated reasoning components used in CBM systems.
