This Final Report of 109 pages describes the successful application of the above-mentioned technique involving computerized intermittent or continuous assessment of stressed machinery in terms of the different types and levels of noise it generates over a period of time. This results in more efficient maintenance operations leading to higher reliability levels at reduced cost. The essential elements of the study involve using real time Body Noise Analysis to establish current noise levels and then provide an ongoing and recorded assessment of the condition of individual machines by detecting subsequent changes in noise and vibration levels brought about by, for example, excessive rotation speeds, deterioration of gear wheel and bearing geometry conditions, etc. The Report includes the software and hardware requirements and the measurement techniques employed. The Report is based upon five pilot trials in the Ruhr coalfield and its findings indicate the possibility of early fault recognition, improved preventative maintenance procedures, improved management of spare part requirements, the provision of an alarm system for serious situations and the establishment of a data bank of typical noise and vibration characteristics. Another benefit is the possibility of quantifying design improvements, e.g. improved balancing of rotating elements.
