.Modelica.Mechanics.MultiBody.Examples.Constraints.UniversalConstraint .Modelica.Mechanics.MultiBody.Examples.Constraints.UniversalConstraintThis example demonstrates the functionality of constraint representing universal joint. Each of two bodies is at one of its end connected by spring to the world. The other end is also connected to the world either by universal joint or by appropriate constraint. Therefore, the body can only perform rotation about two revolute axes depending on working forces.
Simulation results
After simulating the model, see the animation of the multibody
system and compare movement of body connected by joint (blue
colored) with movement of that one connected by constraint (of
green color). Additionally, the outputs from
sensorConstraintRelative depict position deviations in
the constraining element.
