-
From the Connections section of the action bar, click
Spring
.
- Optional:
Enter a descriptive
Name.
-
Select the geometry supports to connect: Support 1 and
Support 2.
These supports may be one or more faces or edges, or a single point. Leave the
Support 2 field empty if you are defining a spring to ground.
-
Enter the axial spring Stiffness.
This value is the spring constant (force per relative displacement).
-
From the Spring type options, select Linear
Axial.
-
Select an axis system and an axis.
Option | Description |
---|
Global |
Aligns the local feature triad with the global coordinate system. |
Local |
Aligns the local feature triad with a selected axis system in the
model. |
Specify |
Allows you to orient the local feature triad directly. Right-click the feature
triad glyph on the model to orient the local feature triad. |
-
From the Coupling type options, select one of the
following:
Option | Description |
---|
Kinematic |
Directly couples edge or face supports to the motion of a reference point.
|
Continuum distributing |
Couples the displacement and rotation of the fastening points to the average
displacement of the nodes. |
Structural distributing |
Couples the displacement and rotation of the fastening points to the average
displacement and rotation of the nodes. |
-
On the Elasticity tab, enter the spring constant (force per
relative displacement) for Stiffness 1.
-
On the Ref. Length tab, enter the Length associated
with Tx, which is the axial distance between supports for which the spring
force is zero.
Reference lengths define the constitutive response for spring elements generated by
this feature. You can define the translational position at which constitutive forces are
zero by specifying the reference length. The app
calculates the default value for the reference length automatically from the initial
geometry.
-
Optional: Click Update Mesh to see the mesh created
for the spring.
-
Click OK.
