Creating a Mount/Bushing

From the Machine Elements section of the action bar, click Mount/Bushing

.

From the Location section, specify how to locate or position the bushing in the mechanism:

Specify the Outer Sleeve, which is the first attachment location on the connecting body or ground.
Specify the Inner Sleeve, which is the second attachment location on the connecting body or ground.
Both the position and the orientation of the two markers specifying the Outer Sleeve and Inner Sleeve must be identical in the unloaded state of the bushing. Therefore, any translatory or angular displacement between these markers will directly cause a force in this direction.
From the Axis options, select X, Y, or Z to define the bushing axis.
The Outer Sleeve orientation is taken as the reference for the axis directions.
From the Tilting angle options, select one of the following:

Option	Description
Small	Applies a small tilting angle between the markers. Use this option if the tilting angle of the bushing remains smaller than 10 degrees in your application.
Large	Applies a small tilting angle between the markers.

In the Properties section, define the stiffness and damping properties in the respective direction:

Clear the Same in radial and tilting directions check box if the stiffness or damping properties are different for different radial and/or tilting directions.
Select Free axis rotation to define free rotation about the bushing axis (if you select this option, the torsion properties are assumed to be zero).
Free rotation means that the forces in the torsional direction are considered to be zero.
In the table, enter values for Parallel Stiffness and Parallel Damping in the respective direction (radial, axial, tilting, torsion). In each direction, you can select Value input to enter a constant value for the stiffness and damping or Function to define nonlinear stiffness and damping characteristics.
For the stiffness characteristics, you must define the function either as a force over a length or as a force over an angle, depending on the considered direction. For the damping characteristics, you must give the function as a force over the velocity or angular velocity.

The name of the table parameters may change depending on what you selected for the Axis and Tilting angle.
