Docking Cone Positioning The Docking Cone Positioning model defines a Docking cone connection between a Body and an earth connection. Model characteristics and limitations: The model will give a contact force when a point (representing the tip of a docking pin) enters into a cylinder and comes in contact with the internal cylinder walls. It will be detected if the entry into the cylinder opening is successful or not. Until a successful entry is made, the model will give zero forces. Rotation symmetric stiffness around the longitudinal axis is assumed. The contact force acts normal to the internal surface of the cylinder (which can be conical). The transverse relative motion between the two will be limited by the radial clearing at the respective axial distance, \(\Delta z\) , see figure below. Outside this limit, structural stiffness will give a restoring force directed towards the centre. Max radial distance is used to check if the docking cone is entered Force and damping are extrapolated outside the specified radial distances Figure 1.
