Dynamic Event

Use the Dynamic Event tool to define a dynamic (Modal Transient (MTRAN)) loadcase to solver and analyze squeak and rattle occurrences.

  1. From the SnRD ribbon, Setup group, select the Dynamic Event tool from the Dynamic Event tool group.
    Figure 1.
  2. Optional: From the guide bar, click to define loadcase options.
  3. In the modeling window, select one or more nodes where the load should be applied.
  4. In the microdialog, select the required load type.
  5. For Load Curve, select a curve type.
    • Sine Sweep: Defines a SineSweep curve.
    • From File: Import a load curve data in time domain from an external file.
    • From PSD: Select a PSD curve and SnRD will convert it to time-domain.
    • From Curve: Select curve(s) TABLED1, which already exists in session.
  6. Optional: To visualize curves, click to open the Curve Editor dialog.
  7. Click Load Direction(s).
  8. Optional: Click to define scaling and other options.
  9. From the guide bar, complete one of the following options:
    • Click to create the dynamic event and remain in the tool.
    • Click to create the dynamic event and exit the tool.
    • Click to exit the tool without creating the dynamic event.
A dynamic event loadcase is created at the selected node. All the relavent cards are automatically created and listed in the Model Browser.
