A fixed joint is a zero degree-of-freedom constraint. It applies a rigid connection
between the connecting bodies, meaning bodies connected by a fixed joint are forced to move
together. Fixed joints can be used to simulate connections where relative displacements are
idealized to zero, such as bolted connections, welded connections, and bodies that are fixed
in motion and orientation with respect to another body.
-
If the Joints panel is not currently displayed, select the desired joint by
clicking on it in the Project Browser or in the modeling window.
The Joints panel is automatically displayed.
-
From the Connectivity tab, click Body
1 and pick a body from the modeling window, or double-click Body 1 to open the Model Tree (from which the desired body can be
selected).
Note: If the selected joint is a pair entity, first distinguish between the
Left and Right tabs in the
panel, and then edit the properties. When defining a pair joint, use pair
entities for Body, Origin, etc.
-
Similarly, click Body 2 and
select the desired body from the modeling window (or use
the Model Tree).
-
Click the Point
collector (under Origin) and select a point from the modeling window, or double click the
Point collector to open the Model Tree (from which the desired point can be selected).
If editing a compliant joint, see Edit Compliant Joints or Bushings. To edit user-defined
properties, see Edit User-Defined Joints.
