Information

This example shows the two different ways how force laws can be utilized:

• In the left system a body is attached via a prismatic joint to the world frame. The prismatic joint has two 1-dimensional translational flanges (called "support" and "axis") that allows to connect elements from the Modelica.Mechanics.Translational library between the support and the axis connector. The effect is that the force generated by the 1-dimensional elements acts as driving force in the axis of the prismatic joint. In the example a simple spring is used.
  The advantage of this approach is that the many elements from the Translational library can be easily used here and that this implementation is usually more efficient as when using 3-dimensional springs.
• In the right system the same model is defined. The difference is that a 3-dimensional spring from the Modelica.Mechanics.MultiBody.Forces library is used. This has the advantage to get a nice animation of the force component.
