Bir dizel gemi jeneratörünün operasyonel modal analizi

In this study, one of the experimental modal analysis methods called Operational Modal Analysis (OMA) which is conducted in order to obtain modal characteristics of a running system when the excitation forces are unknown and the system is in ambient conditions, has been applied on a marine diesel generator set. In the study, the vibration time datasets have been recorded without detaching the genset from the foundations in ambient conditions and the modal frequencies with harmonics have been obtained using the method of singular values decomposition of power spectral densities.
