SS-T: 4005 Structural Sequential

Run structural sequential (loading and unloading) analysis.

Prerequisites
Some features used in this tutorial are only available in SimSolid Advanced version. Please switch to Advanced to complete this tutorial.
Purpose
SimSolid performs meshless structural analysis that works on full featured parts and assemblies, is tolerant of geometric imperfections, and runs in seconds to minutes. In this tutorial, you will do the following:
  • Learn how to setup structural sequential analysis.
  • Review results of sequential loading and unloading.
Model Description
The following model file is needed for this tutorial:
  • tension_clip.ssp
The model is a 6-part tension clip assembly.

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 tension_clip.ssp
  4. Click OK.

Create Structural Linear Analysis

On the main window toolbar, click Structural Analysis > Structural linear.
The new analysis appears in the Project Tree under Design study 1 and the Analysis Workbench opens.

Create Immovable Support

  1. In the Analysis Workbench, click Immovable Support .
  2. In the dialog, verify the Faces radio button is selected.
  3. In the modeling window, select the faces shown in Figure 1.


    Figure 1.
  4. Click OK.

Create Nut Tightening Load

  1. In the Analysis Workbench, click Nut Tightening .
  2. Select the nut.


    Figure 2.
  3. For Thread pitch, enter 1 mm.
  4. Select the Target axial load radio button and enter 3000 N.
  5. Click OK.

Create Sequential Analysis (Loading Step)

  1. On the main window toolbar, click Structural Analysis > Structural sequential.
  2. In the Structural sequential setup dialog, ensure Structural 1 is selected and click OK.
    The new analysis (Structural 2, Linked to Structural 1) appears in the Project Tree under Design study 1 and the Analysis Workbench opens.

Create Sequential Force

  1. In the Analysis Workbench, click > Force/Displacement.
  2. In the dialog, ensure the Faces radio button is selected.
  3. In the modeling window, select the face shown in Figure 3.


    Figure 3.
  4. For Y direction Force, enter 1000 N.
  5. Click OK.
    The new force, Force/Displacement 1, appears in the Project Tree. Vectors representing the load are shown in the modeling window.

Create Sequential Analysis (Unloading Step)

  1. In the Project Tree, right-click on Structural 2, Linked to Structural 1 and select Create linked analysis > Structural sequential from the context menu.
    The new analysis (Structural 3, Linked to Structural 2) appears in the Project Tree under Design study 1 and the Analysis Workbench opens.
  2. Remove Force from the unloading step.
    1. In the Project Tree under the Structural 3 analysis, right-click Force/Displacement 1 and select Edit from the context menu.
    2. Edit the Y direction Force to 0 N.

Run Design Study

Solve all analyses in the design study.

  1. In the Project Tree, select Design study 1 branch.
  2. Click Run All Analyses .
  3. In the Solver Manager, verify all analyses are selected.
  4. Click Solve.
    SimSolid runs all analyses in the design study branch. When finished, a Results branch for each analysis appears in the Project Tree.

Compare Results

Review the results for Structural 1, Structural 2, and Structural 3.
Structural 1 simulates pre-tensioning of the nut, Structural 2 simulates loading the part, and Structural 3 simulates unloading.
