VIBRATION MEASUREMENT OF FLEXIBLE NARROW TUBE UNDER ACOUSTIC EXCITATION

 Flexible narrow tubes are used in periodic structures to develop mechanical vibration filters. These structures have very thin walls and measuring modal parameters is quite challenge using electromagnetic excitation methods. This study discusses the acoustic source as vibration excitation to a flexible tube. A test setup is developed by modifying impedance tube and measured vibration response using laser vibrometer
