Defining a fluid inflator activation interaction

A fluid inflator activation interaction allows you to activate the inflation of fluid into a fluid cavity to model the flow characteristics of inflators used for airbag systems.

Before you begin: You must create a fluid cavity and fluid inflator interactions.

  1. From the main menu bar, select Interaction Create .

    Tip: You can also create a fluid inflator activation interaction using the tool in the Interaction module toolbox.

  2. In the Create Interaction dialog box that appears, do the following:
    1. Name the interaction.

      For more information about naming objects, see Using basic dialog box components.

    2. Select the step.

      Fluid inflator activation is active only in dynamic steps.

    3. Select the Fluid inflator activation type of interaction.
  3. Click Continue to close the Create Interaction dialog box.

    Abaqus/CAE opens the Edit Interaction dialog box.

  4. Select an Inflation time amplitude to define a mapping between the inflation time and the actual time.

    Tip: Alternatively, you can click to create a new amplitude. For more information, see The Amplitude toolset.

  5. Select a Mass flow amplitude to modify the mass flow rate.

    Tip: Alternatively, you can click to create a new amplitude. For more information, see The Amplitude toolset.

  6. Specify a list of Fluid inflators that need to be activated in this step.
  7. Click OK to create the interaction and to close the editor.

    Symbols that represent the fluid inflator activation interaction that you just created appear in the viewport. For more information, see Understanding symbols that represent interactions, constraints, and connectors.
