Review E-Line Table

Review, edit, and update parameters for all E-Lines and map material compatibility data to squeak lines.

From the SnRD ribbon, Setup group, select the Review E-Lines tool from the Manage E-Lines tool group.
Figure 1.

The Review E-Line dialog opens.

Use the Review E-Lines table to:
  • Get an overview of all the E-Lines in model.
  • Edit and update E-Lines parameters for a single or multiple E-Lines (see Manage E-Lines Options).
  • Review and update Gap and Tolerance values for Interfaces or Map Interface Names from imported DTS file.
  • Map Material to Squeak E-lines.
    Figure 2.
Use selection tools to select and highlight specific E-Lines-
  • - Delete E-Lines.

    This removes selected E-Lines from model.

  • - Realize E-Lines.

    When you edit and update a parameter for a realized E-Lines, the line status changes to unrealized. For such changes, you will have to re-realize the updated line.

  • - Renumber E-Lines.
    To renumber selected E-Lines:
    1. Specify an interval.
    2. Click on
    Note: Last four digits of ID is unable to edit and will be set and controlled automatically. Smallest E-Line ID is therefore 10000.

Material Mapping

You can use the existing template materials or extract information from Ziegler PEM Material Database. Both contain data referring to pairs of material and their compatibility. This data is obtained by stick-slip testing and is used in evaluation of the squeak simulation (Squeak Evaluation).

The idea behind mapping of materials is to incorporate information coming from the material database, without interfering with the cards of existing materials of the model in hand. You must associate materials of parts at the interfaces you want to study to materials in the database. This is done to assign stick-slip testing results to an E-Line which is then used in post-processing of the E-Lines for squeak evaluation.
  • Map Material using template values:
    1. Assign Main and Secondary material for each squeak E-Line.
      Note: Not all material combinations have a match, some combinations have a non-existent risk of Squeak, Impulse Rate range for these are 100-100.
  • Map Material using user defined Material Compatibility Matrix:
    1. Load Material file using Import (unless already done).
    2. Assign the imported Main and Secondary material for each squeak E-Line by selecting them in the table.
  • Map Material when using data from Ziegler Database:
    1. In the Material Mapping tab, click .
    2. Select E-line to Map Material.
    3. Select Type, Manufacturer, and Brand for both Main and Secondary Material.
      Figure 3.
    4. Click to map the selected material pair to the selected E-Lines.
