Primitive joint with misaligned base and follower axes containing one translational degree of freedom
First Generation/Joints/Disassembled Joints
The Disassembled Prismatic block represents a single translational degrees of freedom (DoF) along a pair of specified misaligned axes between two bodies. Simscape™ Multibody™ simulation automatically assembles (aligns) the translation axes at simulation start when it defines a machine's assembled configuration.
Disassembled Prismatic Axes of Follower (blue) and Base (red)
The Advanced tab is optional. You use it to control the way Simscape Multibody simulation interprets the topology of your schematic diagram.
In a closed loop, the simulation internally and automatically cuts one and only one joint.
If you want this particular joint to be weighted preferentially for cutting during the simulation, select the check box. The default is not selected.
The dialog has two active areas, Connection parameters and Parameters.
When you connect the base (B) connector port on the Disassembled Prismatic block to a Body CS Port on a Body, this parameter is automatically reset to the name of this Body CS. See the following figure, Disassembled Prismatic Base and Follower Body Connector Ports.
When you connect the follower (F) connector port on the Disassembled Prismatic block to a Body CS Port on a Body, this parameter is automatically reset to the name of this Body CS. See the following figure, Disassembled Prismatic Base and Follower Body Connector Ports.
Disassembled Prismatic Base and Follower Body Connector Ports
There is one Axes tab.
The entries on the Axes tab are required. They specify the directions of the two misaligned axes of the translational DoF that the Disassembled Prismatic represents.
This column automatically displays the names of the two misaligned translation axes attached to base and follower bodies, respectively.
Enter here as two three-component vectors the two misaligned
directional axes along which the base and follower bodies respectively
can translate. The default vectors are
[1 0 0] and
1 0], respectively. The axes are directed vectors whose
overall signs matter.
Using the pull-down menu, choose the coordinate systems (World,
the base Body CS, or the follower Body CS) whose coordinate axes the
two vector axes of translation are oriented with respect to. The defaults
