Define the Friction
The friction torque resists rotation of the bodies relative to one another. The friction model supports stiction and sliding effects as well as a measured friction torque due to preload in the bushing.

HvTrans is a result translator for HyperView that translates solver result files to .h3d files.
The Altair GUI Toolkit is a resource tool for coding Tcl/Tk dialogs. It contains documentation of the HyperWorks commands, demo pages that illustrate our Altair GUI standards, and sample code for creating those examples.
The HyperWorks Cleanup Utility is a script for Windows that removes any custom settings that you may have due to HyperWorks.
The Model Identification Tool, known as HyperWorks, is a profile in HyperGraph for fitting test data from frequency- and amplitude-dependent bushings to analytical models. The HyperWorks operates in conjunction with HyperGraph, MotionView and MotionSolve to provide you with a comprehensive solution for modeling and analysis.
This section explains how to start the HyperWorks interactively and in batch mode.
This section explains how to use the features in HyperWorks.
The Altair Bushing Model is a library of sophisticated, frequency- and amplitude-dependent bushing models that you can use for accurate vehicle dynamics, durability and NVH simulations. The Altair Bushing Model supports both rubber bushings and hydromounts.
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.
The friction torque resists rotation of the bodies relative to one another. The friction model supports stiction and sliding effects as well as a measured friction torque due to preload in the bushing.
Use Mount Stiffness when you want to approximate the structural deflection of the bodies that the bushing connects due to the load that the bushing carries. Mount stiffness is modeled as a set of linear springs and dampers in series with the bushing stiffness and damping, thus softening the connection between the bodies. Alternatively, you can use flexible bodies to model the bodies the bushing connects.
You can activate Mount Limits to simulate material contact between the bodies that the bushing connects. This contact limits the bushing deflection. When the deflection is sufficient in a given direction to close the gap distance, the mount limit forces or torques become active. The forces and torque are computed using an impact function. An exponent greater than one (1) provides increasing stiffness with penetration. The damping force is smoothed with a cubic step function over the penetration distance.
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.
