Research output: Contribution to journalConference articlepeer-review


Structure identification by transient vibration testing is investigated by modal analysis to orthonormalize the modal vectors. This is possible only if the parameters of the excitation are determined when the frequency response functions are obtained. From free decay testing, the modal vectors are obtained by modal analysis but in an orthogonal form, for which the structure identification is undetermined. This is resolved by modifying the structure that leads to a new set of values which give supplementary equation for the system.
