The use of Operating Deflection Shapes (ODS) to model the,

An operating deflection shape contains the overall vibration for two or more DOFs on a structure. An ODS therefore contains both forced and resonant vibration components whereas a mode shape characterizes only the resonant vibration at two or more DOFs [2]. Real continuous structures have an infinite number of DOFs and an infinite number of modes.MODEL UPDATING USING OPERATING DEFLECTION SHAPES,The updating procedure can be based on mode shapes or on operating deflection shapes. The operating deflection,MODEL UPDATING USING OPERATING DEFLECTION SHAPESModal Analysis and Operating Deflection Shape,,Modal Analysis and Operating Deflection Shape. In the process of diagnosing rotating machinery, it may become unavoidable to do some structural vibration analysis as well. Most often this is done by performing ODS (Operating Deflection Shape Analysis) or Modal Analysis.

Modal and Operating Deflection Shape Testing, Applications,

Operating deflection shape (ODS) analysis takes this a step further and shows the deformation of a structure at specific frequencies. ODS shows the response of a structure to both resonant and forced vibration, and is often very representative of the real world data.Determining Operating Deflection Shape Using the RION SA-78,The operating deflection shapes are displayed by post-processing the data by one of a number of available graphics programs. The SA-78 also offers octave analysis, waveform analysis, and measurement up to 80 kHz to support ultrasonic analysis.Shaker based Operating Deflection Shape(ODS) Testing of,,An operating deflection shape contains the overall vibration for two or more DOFs on a machine or structure. That is, the ODS contains both forced and resonant vibration components.Robert J Sayer[2] explained that, ODS is a vibration testing and analysis procedure, is capable of producing animations of a vibrating mechanical system.

Local damage detection using the two-dimensional gapped,

The above procedure can be applied to the operating deflection shape for a single frequency. However, it is better to apply the procedure to broadband FRF data, and frequency average the results, with the maximum number of operating deflection shapes (and thus, analysis frequencies) being limited to the number of spectral lines in each FRF.DAMAGE ASSESSMENT IN A WALL STRUCTURE USING,qualitative approach would be to compare the operating deflection shapes (ODS).
