Aircraft vibration from React to Predictifasd2024 Tracking Number 88 Presentation: Session: Data-driven testing Room: Room 1.1 Session start: 16:00 Thu 20 Jun 2024 Hoang Thien Phu VO thien-phu.vo-hoang@airbus.com Affifliation: Völker Johannes hans-hermann.voelker@airbus.com Affifliation: Topics: - Environmental Dynamics and Aeroelasticity (High and low fidelity (un)coupled analysis methods:), - Ground Vibration Testing of Aircraft (Experimental methods) Abstract: Aircraft vibration is a natural occurrence due to various sources such as engine operation, aerodynamic forces, system abnormality and mechanical components. Today, aircraft vibration is a ‘burden’ for airlines due to its cost & long troubleshooting. This article will present the Data Based process for identifying, continuously monitoring vibration source(s) and then predicting the coming vibration event(s) , so called Predictive Maintenance for Vibration. Within this process, existing aircraft sensors (low quality and low sampling rate) will be processed and compared with a vibration database, flight by flight, for detecting any abnormal vibration. The vibration database has been built based on several ground/flight dynamic tests and validated aeroelastics models. |
