Constrain the Vehicle

Constrain the Vehicle

Click Create vehicle constraint/contact to create vehicle constraint and contact. All the options available on "Vehicle constraint/contact" input panel are optional.

Select "Constrain bottom rigid plate" option as shown below in red highlighted box (1) to constrain the bottom rigid plate in all DOFs (including rotations) except X-translations.

Select "Create *CONSTRAINED_EXTRA_NODE" option as shown below in red highlighted box (2) to constrain the vehicle with a rigid plate using *CONSTRAINED_EXTRA_NODES. Use "Constrained extra node set" to provide a node set for *CONSTRAINED_EXTRA_NODES.

Alternatively, "Create *CONSTRAINED_RIGID_BODIES" option as shown below in red highlighted box (3) can be used to constrain the vehicle on a rigid plate. If this option is selected, use "Const. rigid body parts" to provide parts for the *CONSTRAINED_RIGID_BODIES.
