ARTeMIS Modal - Operating Deflection Shapes - ODS

ARTeMIS Modal includes time as well as frequency domain Operating Deflection Shapes (ODS). These features allow you to study the overall vibration pattern either over a time segment or at a specific frequency.

ODS analysis is very beneficial in combination with Operational Modal Analysis as it determines and visualizes the combination of the actual forcing functions acting on the structure and the dynamic behavior of the structure. Results can be shown as displacement, velocity or acceleration in SI, Imperial or user-defined units (Time Domain ODS). Decimation and various filters (low-pass, band-pass, band-stop and high-pass) can be applied to frequency limit the analysis.

Both time and frequency domain ODS are available in all versions of ARTeMIS Modal.

Frequency Domain Operating Deflection Shapes

 

Benefits

The benefits of Frequency Domain Operating Deflection Shapes in ARTeMIS Modal are:

  • Frequency domain animation of all test setups using multiple reference estimation.

  • Unscaled or scaled animation using phased assigned spectrum with a specific reference.

  • Pick a frequency to animate the shape on various spectral diagrams or time-frequency spectrograms.

  • View the animation as a movie or step through the movement, frequency step by frequency step.

  • Store shapes for specific frequencies in a Shapes list.

  • The measurements can be signal processed using the same Signal Processing Control dialog as used by the modal analysis techniques.

  • AVI movie creation of animations.

  • Available in all versions of ARTeMIS Modal.

 

Time Domain Operating Deflection Shapes

The benefits of Time Domain Operating Deflection Shapes in ARTeMIS Modal are:

  • Time domain animation test setup by test setup of all frequency content.

  • Acceleration or velocity measurements are automatically integrated to allow displacement animation.

  • Pick a segment in time to animate.

  • View the animation as a movie or step through the movement, time step by time step.

  • The measurements can be signal processed using the same Signal Processing Control dialog as used by the modal analysis techniques.

  • AVI movie creation of animations.

  • Available in all versions of ARTeMIS Modal.
