Abstract:

Sound and vibration signals have been useful for many years in judging the internal condition of machinery and structures. At the Research and Development Center, the interpretation and use of such signals is being developed from an art into a diagnostic technique. This technique, Mechanical Signature Analysis, uses external measurement of sound and vibration signals to diagnose internal condition or malfunctions and to detect incipient failure. Mechanical Signature Analysis has great potential as a unique tool for increasing the reliability and maintainability of a wide range of components, assemblies, and systems. This report discusses some of the fundamental ideas and their application to practical problems.
