Vibration Operating Deflection Shape (ODS) analysis Operating Deflection Shape (ODS) analysis is a highly detailed motion study to determine root cause(s) of complex vibration issues of a machine and as needed, its accompanying foundation, platform, piping, ductwork etc. Interviews with customer and preliminary testing and will determine the size and scope of the ODS model for optimum results. An ODS scale model of the test subject is created in the ODS software. Hundreds of frequency, amplitude, and phase measurements are recorded to animate the model with true in-service data. The model is animated at all applicable frequencies around.
