Direction of the prismatic joint is determined by r[2]
,
which is a vector pointing from frame_a
to
frame_b
.
Optionally, two additional one-dimensional mechanical flanges (flange
flange_a
represents the driving flange and flange
support
represents the bearing) can be enabled via
parameter useFlange
. The enabled flange_a
flange can be driven with elements of the
Modelica.Mechanics.Translational
library.
In the "Initialization" block, elongation s
of the joint, velocity of elongation v
as well as
acceleration of elongation a
can be initialized.
It can be defined via parameter (in "Advanced" tab)
stateSelect
that the relative distance s
and its derivative shall be definitely used as states by setting
stateSelect = StateSelect.always
.
In "Animation" group, animation parameters for this model can be set,
where zPosition
represents the model's position along
the z axis in 3D animation. Some of the values can be preset
by an outer PlanarWorld
model.
