Flange_b(right) 1D translational flange (flange axis directed OUT OF cut plane) 
SystemModel["Modelica.Mechanics.Translational.Interfaces.Flange_b"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This is a flange for 1D translational mechanical systems. In the cut plane of the flange a unit vector n, called flange axis, is defined which is directed OUT OF the cut plane. All vectors in the cut plane are resolved with respect to this unit vector. E.g. force f characterizes a vector which is directed in the direction of n with value equal to f. When this flange is connected to other 1D translational flanges, this means that the axes vectors of the connected flanges are identical.
The following variables are transported through this connector:
s: Absolute position of the flange in [m]. A positive translation means that the flange is translated along the flange axis. f: Cutforce in direction of the flange axis in [N].
