摘要

Many Condition Indicators have been implemented, yet success has been limited owing to their sensitivity to artifacts that invariably corrupt vibration measurements under real-life operations. Here we report a novel approach based on a stochastic non-linear fault evolution model. This probabilistic machine learning algorithm estimates fault magnitudes and probabilities, which were compared to component removals validated by tear down analyses, and achieved a 94% consistency rate over all available data thanks to excellent artifact rejection. This novel maintenance support tool can detect hidden conditions early while virtually eliminating NFF (false positives).
