Defining Connection Elasticity

You can use connection elasticity to define spring-like elastic behavior.

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

About Connectors
  1. From the Force/Moment options, select Fx, Fy, Fz, Mx, My, Mz to define elasticity in one or more degrees of freedom.
  2. Define the Translational stiffness type or the Rotational stiffness type for each component of relative motion you selected in the previous step.
    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.
    Rigid Constrains the displacement/rotations.
  3. Optional: If you selected the Linear stiffness type and have frequency-dependent data, select Frequency dependent data.
  4. 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.
  5. Enter stiffness data for each component.
