Abstract : The main objective of this program was to develop a means for the detection and prediction of a particular class of mechanical failure through the use of indirect measurements. The failure mechanism of interest in this program is gear wear. This was selected because it limits the problem to manageable proportions, is a reasonably important source of failure in mechanical systems, and because the effect of gear wear on indirect measurement is analytically describable. The design of a detector for mechanical failures is divided into two phases: signal generation and signal detection. In the signal generation phase an attempt is made to establish a correlation between an indirect measurement of a physical condition of interest, and the occurrence of the particular condition. In the signal detection phase, an attempt is made to design a detector which automatically detects the presence of the desired signal. (Author)
