VIBRATIONS EXPERIMENTAL LAB

 

Immagine1

Developments of experimental modal analysis technique based on both input/output and output-only measurements. Identification of structural dynamic properties from flying test and GVT of fixed wing and rotating wing vehicles. Environmental testing for design qualification and flight acceptance of space structures and mechanical components undergoing severe vibration level. Vibration reduction methods via PZT patches passively used. Developments of sensitivity based structural updating techniques and structural damage identification methods.
Environmental Testing
Dongling Air-Cooled Vibration Test composed by:
