Abstract:

Automated screening of machinery problems and their effect on machinery health and life expectancy, is an achievable and cost effective goal. Expert computer systems with automatic screening, and operator interface will enhance this decision making process. This discussion includes 1 the development of a smart computer aided analysis system and our proposed expert system, 2 a set of hierarchical production rules for machinery vibration analysis and 3 a tabulated Vibration Diagnostic Guide. Keywords Patterns Structureborne noise Acceleration Velocity Shaft rate series Rotating machinery Residual imbalance Mass imbalance Machine resonance System resonance Matrix History Spectra Average files Baseline Continuum Cepstrum Combing CouplingInteraction.
