Paper Abstract

In the present paper, modal characteristics and vibration control performance of smart hull structure are experimentally investigated and compared between in the air and underwater conditions. End-capped hull structure is manufactured and Macro Fiber Composite (MFC) actuators are attached on the inside surface of the structure. Natural frequency and mode shapes are experimentally investigated for each in the air and underwater conditions. For the verification of modal test results, finite element analysis is conducted and numerical results are compared with modal test results. Optimal controller is designed and then implemented for vibration control of smart hull structure. Structural vibration control performances are evaluated in the air and underwater conditions and presented both in frequency and time domains.
