Damage Theory

The running system is the key part to finish training or battle tasks of complicated equipments. But formidable working conditions influence the measurement of load spectrums and it is difficult to analyze and forecast the reliability of running system. Actual vehicle experiments and virtual prototype are firstly combined to obtain complete load spectrum of running system. According to the materials S-N curve, stress and strain spectrums can be computed. Nominal stress method and local stress and strain method are combined with probability density accumulation damage theory to compute the probability density distribution function. Then, the reliability of running system can be forecasted, which provide adequate reference for the maintenance cycle confirmation and mission reliability prediction.

The Cost

Currently, repair and maintenance cycles that follow the completion of construction facilities lead to the necessitation of subsequent data on the analysis of study and plan for maintenance. As such, an index of evaluation was drafted and a plan of maintenance cycle was computed using the investigation data derived from surveying target housing units in permanent rental environmental conditions, with a minimum age of 20 years, and their maintenance history. Optimal maintenance and replacement methods were proposed based on this data. Economic analysis was conducted through the Risk-Weighted Life Cycle Cost (RWLCC) method in order to determine the cost analysis of maintenance life cycle methods used for repair. Current maintenance cycle methods that have been used for 20 years were also compared with alternative maintenance cycles.

The Crew Survivability and Logistics Division of the Air Force Research Laboratory (AFRL/HES) is currently directing a program of research focused on enhancing the task environment for programmed depot maintenance (PDM) technicians. One issue being addressed by the Integrated Technical Information for the Air Logistics Centers (ITI-ALC) program is the appropriate insertion of advanced technologies into the PDM task environment. One challenge facing AFRL/HES was to identify those PDM functions for which the insertion of ITI-ALC technologies would be most beneficial. This paper describes how the application of a traditional human factors-based systems analysis led to the identification of these functions.
