From the Preferences menu, you can access the Options dialog.
Explore the various vehicle modeling tools.
The AutoRider models the mass and inertia of a human body and includes graphics for the human body.
The AutoBush is a bushing model that is designed to easily simulate bushings used in ground vehicles. The AutoBush entity reads bushing stiffness (force-displacement) and damping (force-velocity) data from a file written in the TeimOrbit format.
This section provides information about using the Altair Bushing Model, also known as AutoBushFD, with MotionView. The Altair Bushing Model is a sophisticated model that you can use to simulate the behavior of bushings in vehicle dynamics, durability and NVH simulations.
The Model Identification Tool (MotionView) is a utility in HyperGraph that you use to fit experimental data to various bushing models. The MotionView generates a General Bushing System file, .gbs file, which defines the bushing properties.
You can add an Altair Bushing Model, also known as AutoBushFD, a frequency-dependent bushing, to your MotionView model using the Add Auto Entity tool in MotionView.
This section describes how you attach a bushing to a model.
The Properties window includes five tabs that you can use to define the properties of your bushing.
In addition to adding a single bushing to your project, you can also add a pair of bushings such as AutoBushFD pair. When you add a pair, MotionView automatically reflects modifications you make on the left bushing of the pair to the right bushing, unless you choose otherwise. MotionView assumes bilateral symmetry about the global X-Z plane.
The AutoDamper entity is a force-velocity model designed to easily simulate a shock absorber used in ground vehicles. The AutoDamper entity reads force-velocity data from a file written in the TeimOrbit format.
