SS-T: 4085 Squeak and Rattle Analysis

Learn how to create a squeak and rattle analysis in SimSolid and review the status at different points along the model.

Model Description
The following model file is needed for this tutorial:
  • Plates.ssp

Figure 1.
The model (.ssp) file has the following specifications:
  • Material is set to Steel
  • Model analysis and transient dynamic analysis is created

Open Project

  1. Start a new SimSolid session.
  2. On the main window toolbar, click Open Project .
  3. In the Open project file dialog, choose Plates.ssp
  4. Click OK.

Review Model

  1. In the Project Tree, expand Transient Dynamics1 analysis.
  2. Expand the Loads&Constraints branch and review the loads.
    Figure 2.
  3. Click (Results plot) and choose Displacement Magnitude.
  4. Click to view the displacement animation.

Create Squeak and Rattle Analysis

  1. On the main window toolbar, select > Squeak and Rattle.
    The new analysis appears in the Project Tree.
  2. In the pop-up window, select transient analysis to link the squeak and rattle analysis with.
  3. Set the gap tolerances for open-close and stick-slip to zero.

Create Sampling Points

  1. In the Analysis Workbench, click (Add/edit).
  2. In the dialog, switch to the Group connect tab.
  3. In the modeling window, select the parts as highlighted in the image.

    Figure 3.
  4. Set the gap tolerance to 6 mm and the resolution level to Normal.
  5. Click Find.
  6. Review the sampling points found.
  7. Click OK.

Run Analysis

  1. On the Project Tree, open the Analysis Workbench.
  2. Click (Solve).

Review Response

  1. In the Analysis Workbench toolbar, click (Response).
  2. In the dialog, choose the sampling point and set the response type to Final status to review the final states of various points in the selected sampling point set.
  3. Switch the response to Minimal gap to view the minimal normal gap due to the applied excitation.
  4. Select one of the points in the graphics to view a plot for relative distance over time.
