In the browser, right-click the Springs branch, and then select Add Translational Spring.
Right-click one or two moving or ground parts, point to Add Force, and then select Translational Spring.
If not already selected, select the Definition tab.
Select the components to which to attach the spring.
In the first Select Location text box, select a vertex, circular edge, or linear edge on the first component you selected to define the point at which the spring is attached.
In the second Select Location text box, select a vertex, circular edge, or linear edge on the second component you selected to define the other point at which the spring is attached.
Verify
that your first point is on the first component and the second point is
on the second component. If you select the points out of order with the
components, your spring will not behave as expected.
Select a Force Expression type (use default for a linear spring).
In the Stiffness text box, modify the default spring stiffness.
Select the Design button.
If Design is off, you can define the free length of the spring.
If Design is on, the free length of the spring is automatically defined to be the distance between the two points that you selected in the Points panel.
The
free length of the spring is the distance between those points in the
initial position of the assembly.
Define a preload on the spring by entering a value in the Force text box.
Specify the Coil Diameter, Number of Coils, and Wire Thickness.
Select Apply to create the spring and close the dialog box.
