发帖数: 9020 | 1 For modern systems, wear estimation plays an important role
in preventing failure, scheduling maintenance, and improving
utility. Wear estimation relies on a series of sensors, measuring the state
of the system. In some components, the sensors
used to estimate wear may not be fast enough to capture brief
transient states that are indicative of wear. For this reason
it is beneficial to be capable of detecting and estimating the
extent of component wear using steady-state measurements.
This paper details a method for estimating component wear
using steady-state measurements, and describes a case study
of a current/pressure (I/P) transducer. I/P Transducer nominal
and off-nominal behavior are characterized using a physicsbased model, and
validated against expected component behavior. This model is used to
determine steady state responses
to many common I/P Transducer wear modes, isolate the active wear mode, and
estimate its magnitude. |
