Creating Tabular Amplitudes

You can apply tabular amplitudes to define an amplitude curve as a table of values at convenient points on the time scale. You can apply an amplitude curve to a load to allow arbitrary time variations of the load magnitude throughout a step.

Entering Tabular Data
Feature Manager
  1. From the Setup section of the action bar, click Tabular Amplitude .
  2. Optional: Enter a descriptive Name.
  3. Select a Time span for the amplitude.

    Note: You cannot change the time span once the amplitude is created. To change it, you must delete the amplitude and create a new one.

  4. Enter a Smoothing factor.

    The smoothing factor represents the fraction of the time interval before and after each time point during which the piecewise linear time variation is to be replaced by a smooth quadratic time variation. The allowable range is 0.0 to 0.5.

  5. Enter Time/Frequency points and associated Amplitude magnitudes in the amplitude table. You can also import data from an external file by right-clicking in the table.
  6. Click OK.

Tip: To visualize the tabular amplitude data in an X–Y plot, right-click any table cell and select XY plot from the contextual menu.
