Remote Detection of Abnormal Behavior in Mechanical Systems,ishment of fault feature observability as a function of sensor location relative to operating equipment. In this study, the procedure used for fault detection consists of the following: (1) collect signals for rotating machinery operating in a healthy, faulty, and off state (2) identify features tha

This study shows that the cluster centers can be employed to estimate the ODS vectors, and the performance of the proposed methodology is evaluated experimentally on a lab-scale cantilever beam and validated via

Full Field Strain Measurements Using 3D Laser Vibrometry, more traditional, reliable strain measurement techniques. This paper will be comparing the results of the 3D laser vibrometry system’s strain measurements using several different surface treatments at several different temperatures to measurements obtained from traditional foil strain gages.

Output-Only Modal Parameter Estimation Using a Continuously Scanning Laser Doppler Vibrometer Systeethod are: (1) modal damping ratios and mode shapes can be accurately estimated from obtained free response shapes, (2) the scanning frequency of the CSLDV system can be relatively low, and (3) estimated mode shapes can be used for structural damage identification as if they were measured by stepped
