Inertia effect of a moving mass on beam structure for damage identification

초록

The dynamic characteristics of the beam subject to a moving mass are affected by inertia force unlike a moving force. This work considers damage detection of the beam structure evaluating the flexural performance, and the applicability of such basic concept is illustrated in a numerical experiment. The experiment investigates the feasibility of damage detection by the measurement of the inertia force and the output responses without any baseline data. The measurement data are transformed to the proper orthogonal modes (POMs) in the time domain. It is shown that the proposed method can be practically utilized by reducing the effect of the external noise. © Research India Publications.
