Improved Maintenance of Machinery Through “Baseline” Vibration Measurements

The purpose of this paper is to present a method for increasing the value of vibration analysis as a tool in the maintenance of machinery. The method, termed “baseline” method, is described and the use of various types of vibration measuring instruments and data recording explained. Seven steps involved in setting up a baseline program are discussed with information provided as to specific measurement and analysis technique. Various applications of the method, designed to expand the usefuless of vibration analysis, are also outlined.
