Components for Bearing Connection Reaction Measures
A bearing connection allows translation and rotation along and around an axis, and rotation around two axes perpendicular to the first axis.
As shown in the illustration below, the Z axis of a bearing connection is fixed to the LCS of the first (green) body and can be positioned anywhere along the bearing translation axis. You can only define meaningful Radial Force X and Radial Force Y measures in relation to the first (green) body LCS. In other words, you cannot define Radial Force X in relation to the bearing translation axis because it is fixed to the first (green) LCS.
You can define the following measures for a bearing connection:
Axial force—the force component as it moves along a translation axis (Force X, Force Y, and Force Z).
Radial force X and Radial force Y—the force component on the plane perpendicular to the Z axis of the connection.
Total Force
Depending on the type of component you are defining in the Definition dialog box, you can expect the following results:
If you select Radial force X or Radial force Y, the axis line of the first (green) body is displayed at the connection icon and the X and Y directions are clearly visible.
If you select Total force, Axial force, or Radial force, the values are scalar and a LCS reference is not necessary.
When Force X, Force Y, or Force Z is selected, the connection icon, the X, Y, and Z directions, and the direction of the force are clearly visible (see below).
When you select the bearing connection and Axial force, a colored arrow appears on the connection indicating the positive direction. Consider carefully whether this direction correctly indicates the force or moment you want to display.
If your model is shaded, the shading may hide the arrow. Select the Wireframe, Hidden Line, or No Hidden display to make the arrow visible.
These forces are displayed in the bearing point when you run the playback file.
