Create and Route Seatbelts

Create and route seatbelts onto a dummy using the Seatbelt panel.

  1. Go to the Analysis page, and click the safety module.
  2. Click the seatbelt panel.
  3. Select the Create subpanel.
  4. Use the node list selector to select the nodes which define the first endpoint, orientation nodes (used to guide the initial belt position) and the last end point of the seatbelt.
    Multiple nodes can be selected as orientation nodes to guide a smooth belt.
  5. Use the wrap around selector to select the entities that you want the seatbelt to be wrapped around.
  6. Choose which type of elements to use when creating the seatbelt.
    • Choose 1D to create the seatbelt with no width, and so on.
    • Choose 2D/1D to create the seatbelt with a combination of 2D and 1D elements.
  7. In the gap field, enter a gap between the belts and the dummy components to avoid any initial penetration.
  8. In the orient sensitivity field, enter value can be modified when in orient mode to change the sensitivity of the interactive movement of the belt segments to mouse movement.
  9. If you selected 2D/1D, define the following settings:
    1. For end type, select whether the end length of the seatbelt will be rigid links (default) or tria surfaces.
    2. In the element size field, enter the density of the mesh for seatbelts.
    3. For mesh type, select whether the mesh of the seatbelt will be quads only (default) or R-trias.
    4. In the belt width field, enter the width (in model units) of the belt.
    5. In the 1d length at start field, enter a distance the 1D elements must extend from the first endpoint of the seatbelt.
    6. In the 1d length at end field, enter a distance the 1D elements must extend from the last endpoint of the seatbelt.
    7. Specify when to display the full seatbelt segment.
      • Choose on release (default) to display the full seatbelt segment upon release of the mouse.
      • Choose real time to display the full seatbelt segment instantaneously.
    8. In the place 1D elems in field, select a collector to place 1D elements that are created.
    9. In the place 2D elems in field, select a collector to place 2D elements that are created.
  10. After you select the desired end list and the wrap-around entities (components, elements, or ellipsoids), click orient or accept.
    • Click Orient to draw a full segment belt representation, which previews the orientation of the final belt. The two red end segments are linear and connect the end points selected to the previous intersection points on the dummy. The middle line segments follow the contour of the dummy and connect the two end segments. You can select each of the line segments and interactively orient them to a specific location. Once the final position is achieved, release the mouse to create a mesh that follows the specified path. The Update subpanel enables you to interactively change/update the element density and biasing.
    • Click accept to eliminate the belt segment preview and directly create a mesh on the belt. You can then interactively change or update the element density and so on.
  11. Click return to exit the panel.
