Use the Clearance Joint for 2D and 3D components to create joints between two components such that they are free to rotate relative to each other about all three axes and free to translate relative to each other within the specified clearance limit.
Select a Source. Select any
Attachment,
Rigid Material,
Spur Gear,
Helical Gear,
Bevel Gear,
Worm Gear,
Spur Rack,
Helical Rack, or
Base Motion that is defined for the model. The option
Fixed is also available. When
Fixed is selected, the source side of the joint is fixed in space, and not connected to any modeled parts. Selecting a base motion gives a behavior similar to using
Fixed, with the exception that the base now can have a nonzero prescribed displacement, velocity, or acceleration.
If the source is Fixed, the only option available is
User defined.
Select a Destination. Select any
Attachment,
Rigid Material,
Spur Gear,
Helical Gear,
Bevel Gear,
Worm Gear,
Spur Rack, or
Helical Rack that is defined for the model. Select a
Connection point —
Centroid of destination,
Centroid of selected entities, or
User defined.
In large models, the list of available attachments can become long. You can then create geometric filters to narrow down the search. When the Use selection filter check box is selected, two subnodes named
Source Filter and
Destination Filter are added to the joint node. In these subnodes you can make graphic selections of the objects whose attachments should be shown in the
Source and a
Destination lists.
Enter a Clearance c. The default is 0 which corresponds to two connection points at the same geometric position. This is equivalent to a ball joint (3D) or a hinge joint (2D).
Enter the Penalty factor pj. The default is
(mbd.crj1.Eequ*(0.1*mbd.diag)). The exact naming of the variable depends on the tags of the nodes in the model tree.
Select Group dependent variables in solver —
From physics interface (default),
Yes, or
No, to choose how to group the dependent variables added by the
Clearance Joint feature in the solver sequence.
