Use a Spring FB to add a force between two Points that are in two different Parts.
The Forces a Spring FB can exert include:
•Spring Force - a force proportional to the difference of the distance between the Spring's Anchor-Point and its Free-Length.
•Constant Force - a constant force that only pulls or only pushes the Spring's Anchor-Points, throughout the machine-cycle.
•Coulomb Constant-Force - a constant force that acts in the opposite direction to the relative velocity between the Spring's Anchor-Point.
•Drag-Force - a force that is proportional to the relative velocity between the Spring's Anchor-Points.
•Drag-Force-Squared - a force that is proportional to the square of the relative velocity between the Spring's Anchor-Points.
See Spring FB dialog-box to edit these parameters.
Terminology:
Anchor-Points : |
The two(2) Points that define an axis through which the Force FB applies its Force. |
Force element : |
A Spring FB is a Force-Element. |
Linear Motive Force : |
The Spring FB can become the Power-Source. It will indicate the Equivalent Linear Force that is needed to drive a Kinematic-Chain. A Linear Motor would need to provide this Force. |
How to add : |

The Spring FB can be in three different states.
State 1: The Spring FB is enabled. The default state. |
||||||||
State 2: The Spring FB is not enabled. To disable the Spring FB, 1.Edit the Spring FB to open the Spring FB dialog-box In the Spring FB dialog-box 2.Deselect the Enable Check-box. 3.Click |
||||||||
State 3: The Spring FB is a Linear Motor To change the Spring as a Linear-Motor
