AN INSTRUMENTATION SYSTEM FOR MEASURING THE STRUCTUREBORNE VIBRATION AND AIRBORNE NOISE OF BEARINGS,

Abstract

Efforts were directed towards the components, calibration and use of an instrumentation system developed for detecting and recording both structureborne and airborne vibrations of rolling contact and sliding surface bearings. The transducers used are a crystal accelerometer for strutureborne vibrations and a condensor microphone for airborne vibrations. Signals from the transducers are fed into suitable analyzing and recording equipment producing frequency analysis results in terms of absolute acceleration and sound pressure over the frequency range from 25 cps to 25,000 cps. The instrumentation system described herein is being used successfully as an integral part of the Bearing Noise and Vibration Test Machine currently in operation. (Author)
