On the use of measured rotational responses in structural dynamic analysis

Testing is a very important task in structural dynamics and on its applications, namely on the characterization of the dynamic behaviour of structures or on the use of the structural responses to indirectly determine dynamic properties or parameters. The increasing availability of sensors, capable of measuring rotational responses, leads to the improvement of existing methods and to the development of new ones in several fields of application. In this work, an evaluation of the applicability and performance of the use of rotational responses is carried out considering applications ranging from the determination of rigid body properties to damage identification. Data acquisition using MEMS and piezoelectric sensors is covered and a set of results is discussed.
