Frequency-Based ODS Animation

With ME'scopeVES, you can animate frequency-based ODS's (Operating Deflection Shapes) directly from data that was acquired from a machine or structure

• During Sine Dwell Sine Dwell in one of the three types of shape animation in a Structure window. During Sine Dwell animation, the displayed shape is animated by multiplying it by sine wave values as a unit circle is tranversed in equal increments from 0 to 360 degrees. . animation, the ODS at a specific frequency is displayed using sinusoidal modulation.

A frequency-based ODS allows you to see how a structure behaves at a single frequency.  While dwelling at a frequency, the ODS will show you where vibration levels are highest, and will indicate loose parts and connections.  A frequency-based ODS can also help you determine whether or not a resonance is being excited, or whether the vibration is an order related forced vibration.
