- Abstract
- In this paper, we propose a diagnostic model of electronic means (ES), based on the complex electrical, thermal and mechanical modeling for high reliability computer-aided diagnosis. The method developed on the basis of this model allows to detect hidden faults and system failures due to the interconnection of electrical, thermal and mechanical processes occurring in the ES. Hidden failures are not reflected in the separate mathematical modeling of physical processes and occur when mathematical modeling of electrical processes is made in view of operating temperatures and mechanical stress of component elements, when their mutual influence on each other.
