ODS (Operating Deflection Shapes)

ODS testing is an extremely useful tool for determining the vibration “shape” of machines and structures. Vibration data is obtained at various points on the structures and the data are animated using the amplitude and phase relationships and the corresponding test points of a 3-D model.

ODS measurements are useful for identifying loose joints, bolt failures, and resonant mode shapes.  This information can often be used to determine modifications to the system to eliminate vibration issues.
