Joint where frame_b is translated around axis n which is fixed in frame_a. The joint axis has an additional flange where it can be driven with elements of the Modelica.Mechanics.Translational library. The relative distance q [m] and the relative velocity qd [m] are used as state variables.
The following parameters are used to define the joint:
n : Axis of translation resolved in frame_a (= same as in frame_b).
n must not necessarily be a unit vector. E.g.,
n = {0, 0, 1} or n = {1, 0, 1}
q0: Relative distance offset in [m].
(in the direction of n).
If q=q0, frame_a and frame_b are identical.
startValueFixed: true, if start values of q, qd are fixed.
