Defining Connection Damping

You can define connection damping to describe dashpot-like damping behavior in a connection.

Before you begin:
  • Create a new connection or edit an existing connection. To create a connection, see Connections.
  • In the connection dialog box, click to open the Behaviors editor.
  • In the left pane of the Behaviors, select Damping.

  1. From the Damping type options, select one of the following:
    OptionDescription
    Viscous Specifies velocity proportional damping.
    Structural Specifies displacement proportional damping. You can use only linear damping behavior with this type.

    See Connector Damping Behavior for more information.

  2. From the Force/Moment options, select Fx, Fy, Fz, Mx, My, Mz to define damping in one or more degrees of freedom.
  3. If you are defining Viscous damping, from the Translational damping type or Rotational damping type options for each active component, select one of the following:
    OptionDescription
    Linear Defines the behavior by a single spring constant.
    Nonlinear Defines the behavior by a table of force/moments at one or more relative displacement/rotations.
  4. Optional: If you selected the Linear damping type and have frequency-dependent data, select Frequency dependent data.
  5. Enter damping data for each component.
  6. If you are entering tabular data, from the Extrapolation options, select one of the following to define how the app handles any data that falls outside the specified range:
    OptionDescription
    Constant Uses the value equal to the nearest end point of the specified data.
    Linear Uses linear interpolation based on the slope of the curve at each end point.
