Electronic Prognostic and Health Management
systems are essential in monitoring electronic
system health by predicting early fault to initiate
a preventive maintenance schedules in civil and
fighter aircraft’s. The accurate prediction of
Remaining Useful Life (RUL) depends on sensor
errors, fidelity of system modelling, inaccuracies
in processing data, prediction of deviations of
actual conditions with that of the simulation
environment. In the current work, a new
methodology of system modeling, simulation
and experimentation of the electronic enclosure
for temperature profiling and structural
integrality has been attempted by suitably
managing internal arrangement of data cards
and sensor modules. The system’s performance
has been characterized under steady and
transient temperature conditions using suitable
measurement and simulation tools. The set up
was subjected to the accelerated thermal profile
to monitor online temperature measurements at
the identified hot spots on the test board. The
measurements of temperature gradients are in a
good match with the simulation results and thus
validates the proposed model under the test
conditions. The system is further tested with the
FEM simulations for vibration profile to estimate
its static and dynamic stress tolerances. The
experimental and model simulation accuracies
establishes a reliable prognosis approach to
integrate physics based models & data driven
models to get more accurate mitigation of
failures to reduce maintenance cost of avionics
equipment.
