Applying Translations

You can use an applied translation to prescribe motion in a single direction by a specified distance.

  1. From the Loads section of the action bar, click Applied Translation .
  2. Select the geometry supports in the model. You can select one or more faces.

    Tip: Change the Selection method to select from a list of publications, connections, or FEM features, including virtual contact interactions.

  3. Optional: Enter a descriptive Name.
  4. Select the geometry supports in the model.

    A translation can be applied to one or more points, edges, or faces. You can also select a coupling connection, rigid body, or rigid surface; the displacement is applied to the reference point for the feature.

    You can apply the translation to a secondary base by selecting Sim feature as the type of support, then selecting the appropriate displacement restraint from the window that appears.

  5. Enter the Translation distance.
  6. Select a Degree of freedom representing the direction of translation within the selected axis system.
  7. Choose whether the Orthogonal translations are Free or Fixed.

    If you choose Fixed, no movement is allowed in the directions orthogonal to the direction of the translation. This effectively creates restraints on the orthogonal directions. For example, if the direction of translation is the global Y-axis direction, no movement is allowed in the global X- or Z-direction.

  8. Select an Axis system representing the local feature triad:
    • Global: Aligns the local feature triad with the global coordinate system.

    • Local: Aligns the local feature triad with a selected axis system in the model.

    • Specify: Orient the local feature triad directly by right-clicking the feature triad glyph on the model and selecting an orientation tool.

    • Implicit: Aligns the axis system to the transformed axis system applied to the support.
  9. For a Local axis system definition, do the following:
    1. Select a custom Axis system by clicking it in the model or in the tree.
    2. Specify the Axis system type as Cartesian or Cylindrical.
  10. Optional: Enter a Scale factor that is applied to the magnitude in each step.
  11. Select an Amplitude that defines the magnitude during the step.
  12. Click OK.
