Abstract:

It has long been understood in the equipment design and development shops of industry, that the useful life of mechanical systems is consumed by an accumulation of damage due to the broad range of stresses to which the system is subjected. Heretofore, measuring the cumulative damage as a means of assessing the remaining life has been impractical, particularly for mobile systems. The advent of microcomputers now makes it possible to keep a running measure of this damage and to use this measure to help optimize the systems continuing reliability. The name Geriometry has been coined to distinguish this process--the measurement of the systems continuing life expectancy. Used in conjunction with trend assessment of the system condition and performance capability, Geriometry provides the most powerful capability yet applied to manage and minimize maintenance resources while maximizing continuing system reliability.
