See Add Spring FB
Use a Spring FB to apply a force between two Points. The name that we use for the two Points is Anchor-Points.
Force units are defined in the Machine-Settings dialog > Engineering Units - default Force units are Newtons (N).

Note: It is not necessary to connect a wire to the input-connector or from the output-connectors of the Spring FB. The input and output-connectors provide extra functionality - see Here |
The Spring dialog is now open.

☑ Check-box to enable the Spring FB. Spring-Rate:
Spring-Length is the distance between the two anchor-points. The Force always tries to move the anchor-point to the Free-Length (They cannot, of course). Free-Length:

Coulomb (Constant) Friction Force (Ff = μ.Fn )
Viscous Coefficient (Fv α V ( N/(mm/s) )
For example, if the Damping Coefficient = 4 and the Velocity is +100mm/s, (anchor points moving away from each other), the force pulling the points together is a force of 400N. Drag Factor (Fd α V2) ( N/((mm/s)2 ) )
For example, if the Drag Factor = 4, and the Velocity = +100mm/s (anchor-points are moving apart), then the force pulling the anchor-points together is a force of 40000N. |
Output-Connectors The Spring-FB has two output-connectors.
