Create Spring Dampers

A spring damper can be a coil spring damper or a torsion spring damper.

1. From the Project Browser, select the system to which the spring damper is to be added.
2. Right-click on a system in the Project Browser and select Add > Force Entity > SpringDamper from the context menu.
   OR
   Right-click on a spring damper folder in the Project Browser and select Add SpringDamper from the context menu.
   OR
   Right-click the Spring Damper button on the Force toolbar.
   The Add SpringDamper or SpringDamperPair dialog is displayed.
3. Specify a label and variable name.
   By default, variables names of entities in MotionView follow a certain convention. For example, all force entities have a variable name starting with “sd_”. This is the recommended convention to follow when building models in MotionView since it has many advantages in model editing and model manipulation.
4. Select whether to create a single spring damper or a spring damper pair.
   A spring damper entity, like most of the entities that are created in MotionView, can be a single entity or a pair entity. Pair entities help in creating models which have symmetric properties.
5. Select a spring damper type from the drop-down menu.

   Option	Description
   Coil Spring	Generates a translational line of action force between two points on two bodies that is a function of the distance and the relative velocity between the two points.
   Torsion Spring	Produces a moment between two bodies that is a function of the relative angular displacement and the relative angular velocity between the two bodies.

6. Click OK to close the window or Apply to continue creating entities.
   Once a spring damper entity has been added to the model, the panel for the spring damper will automatically be displayed in the panel area.
