NullJoint ​

Rigid connection between two frames (zero degrees of freedom).

Simply connects frame_a and frame_b with no relative motion allowed. All positions, orientations, forces, and torques are transmitted directly.

This component extends from PartialTwoFrames

Usage ​

MultibodyComponents.NullJoint()

Connectors ​

  • frame_a - Frame3D is the fundamental 3D connector used for 6DOF motion. Most components have one or several Frame

connectors that can be connected together (Frame3D)

  • frame_b - Frame3D is the fundamental 3D connector used for 6DOF motion. Most components have one or several Frame

connectors that can be connected together (Frame3D)
