Hydraulic System Acoustical Diagnostics.

Abstract

This project is a continuation of previous acoustics studies conducted to determine if the vibration signature of hydraulic components could provide information concerning the operational health of the system. The concept of using internally produced noise to detect incipient failure is not new (the screwdriver-to-the-block trick used by automobile mechanics is a good example); however, the technique has been more of an art than a science, especially where hydraulic systems are concerned. This study advances the previous work by applying the concept to vane pumps into which specific known degradation has been introduced. The study showed that, by using case-mounted accelerometers, significant vibratory differences can be detected and associated with given conditions.
