PrismaticConstraintBody attached by one spring and two prismatic joints or constrained to environment |
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example demonstrates the functionality of constraint representing prismatic 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 two serial coupled prismatic joints or by appropriate constraint. Therefore, the body can only perform translation in two directions specified in the two joints 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 both position and angle deviations in the constraining element.
