Modifying Bushings

This topic shows you how to modify and make specifications for bushings using the Connectivity, Symmetry and Properties options in the MotionView User Interface.

Option

Description

Connectivity

The pane on the UI where you define how your bushing system attaches to your model.

Properties

The pane on the UI that includes five sub tabs from which you enter bushing properties:

•	Property Files: Loads the .gbs property file.

•	Preload/Offset/Scale: Specifies factors that modify forces and torques.

•	Friction: Includes simpler friction models in lieu of complex hysteresis models.

•	Mount Stiffness: Specifies the compliance in the bodies to which the bushing is attached.

•	Mount Limits: Specifies material contact properties to adjust for bushing deformations that become too large.

Symmetry

The field on the UI where you define a symmetric or asymmetric bushing system. Symmetry, if used, is assumed to be about the global X-Z plane.

Example

To define a single, frequency-dependent bushing using the Connectivity, Symmetry and Properties options, do the following.

1.	From the Model browser in MotionView, select the entity AutoBushFD that you created in the topic, Adding the Altair Bushing Model:

auto_entity_browser

2.	The following window appears at the bottom of your screen:

The window includes a Connectivity pane, shown outlined in red, and a Properties pane, shown outlined in green. For more details about the options in each pane, see the links at the beginning of this section.
