Response Graph PropertyManager

The Response Graph PropertyManager allows you to generate a frequency graph of the results at certain locations. Response graphs are available for harmonic and random vibration analyses.

Response

Predefined locations Lists the vertices and reference points you defined as Workflow sensitive sensors.
All nodes Lists all nodes in the model. Available only if you did not select vertices or reference points in the Result Options PropertyManager before running the study.
At remote locations Available when you define a remote mass. Lists these bodies that are treated as remote masses, and nodes where you apply a remote mass.
There are two options for applying a remote mass for a linear dynamic study:
  • In the Remote Loads/Mass PropertyManager, select Load/Mass (Rigid connection). Select Mass and type the value in Remote Mass.
  • Right-click a selected body and click Treat as Remote Mass. Clear Apply Force/Moment at CG. The program displays the results at the center of gravity of a body that is treated as a remote mass.

You can plot a maximum of six response graphs on the same plot.
X-Axis Frequency in Hz (default).
Y-Axis Select stress, displacement, velocity or acceleration results for Y-axis.

Component

Select a component from the menu.

Units

Select a unit for the Y-axis component.

X-Axis Range (Frequency)

Full Select to plot results for all frequency steps.
Defined Select to plot results for a selected frequency range.

Min

Minimum value of frequency range

Max

Maximum value of frequency range

Resolution of Intermediate Points

Set the resolution of intermediate frequency points. For example, if you set 2, results are plotted for every other frequency step.

Options

Amplitude Plots the amplitude of the selected response component.
Phase Angle (deg) Available for X, Y, Z components of displacement, velocity, acceleration response. Plots the phase angle of the response (relative to the applied force) in degrees.
In terms of phase angles, the velocity and acceleration components are +90º and + 180º out of phase with respect to their displacement components.
