Abstract

In this paper OPERATIONAL MODAL ANALYSIS technique is employed in model IDENTIFICATION of a RAILWAY CAR BODY structure which uses recorded responses of the structure for IDENTIFICATION of modal parameters of the body. Since excitation of the RAILWAY CAR BODY with conventional shakers is difficult due to the large mass of the structure, the classical modal analysis techniques are not commonly used for mode IDENTIFICATION of these structures. To overcome this problem a different technique known as OPERATIONAL MODAL ANALYSIS (OMA) which uses responses of the structure during its working conditions is used. Two sets of operational measurements were performed on the structure and results are used to extract mode shapes and natural frequencies of the structure. Validation of obtained modes is performed by comparing the modes obtained from the two sets of measurements.
