A new comprehensive monitoring and diagnostic approach for early detection of mechanical degradation in helicopter transmission systems
Expert Systems with Applications(2022)
摘要
•The transmission system embeds multiple components that are constantly monitored;•Ad-hoc health indexes are extracted from their vibration signature and analyzed;•An ensemble of autoencoders learns the each component's indexes standard behavior;•Anomalies are accurately detected, also reporting the responsible component.
