Advanced bushing supports two modelling methods.
1. General Bushing
2. Nonlinear Bushing
Bushings provide a six degree-of-freedom force relationship for connecting two components. The force is applied between a marker on each component. The force depends on the relative displacement and the relative velocity of the two markers.
The forces generated due to translational and rotational motion are entirely uncoupled from each other. In the description of the bushing formulation that follows, you can apply the force dependencies, described next, to either translational or rotational behavior. Therefore, a statement such as fi = h (relative displacements, relative velocities) implies the following.
■Forces: fi = g (translational displacements, translational velocities)
■Moments: fi = h (angular displacements, angular velocities)
The forces in all six directions are orthogonal and can be coupled in rectangular, cylindrical and spherical ways. For general bushing, the total force from this element is sum of static spline force, TFSISO force, Bouc-Wen hysteresis force, preload and viscous damping force.

For the option: | Do the following: |
|---|---|
Construction | Set the method you want to use to define the bodies and force-application points. You can select the following: ■1 Location ■2 Bodies - 1 Location ■2 Bodies - 2 Locations Learn about Applying Multi-Component Forces to Parts. |
Normal to Grid/ Pick Feature | Set how you want the force oriented. You can select: ■Normal to Grid - Lets you orient the force normal to the current Working grid, if it is displayed, or normal to the screen. ■Pick Feature - Lets you orient the force along a direction vector on a feature in your model, such as along an edge or normal to the face of a part. |
