This kinematic description converts the steady moving contact problem into a pure spatially dependent simulation.

Thus, the mesh need be rened only in the contact regionthe steady motion transports the material through the mesh. The purpose of this analysis is to obtain free rolling equilibrium solutions of a SR14 tire traveling at a ground velocity of The slip angle is the angle between the direction of travel and the plane normal to the axle of the tire.

Straight line rolling occurs at a 0. For comparison purposes we also consider an analysis of the tire spinning at a xed position on a 1.

The drum rotates at an angular velocity of 3. Another case presented examines the camber thrust arising from camber applied to a tire at free rolling conditions. This also enables us to calculate a camber thrust stiffness.

An equilibrium solution for the rolling tire problem that has zero torque, T, applied around the axle is referred to as a free rolling solution. An equilibrium solution with a nonzero torque is referred to as either a traction or a braking solution depending upon the sense of T. Braking occurs when the angular velocity of the tire is small enough such that some or all of the contact points between the tire and the road are slipping and the resultant torque on the tire acts in an opposite sense from the angular velocity of the free rolling solution.

Similarly, traction occurs when the angular velocity of the tire is large enough such that some or all of the contact points between the tire and the road are slipping and the resultant torque on the tire acts in the same sense as the angular velocity of the free rolling solution. Full braking or traction occurs when all the contact points between the tire and the road are slipping.

A wheel in free rolling, traction, or braking will spin at different angular velocities, , for the same ground velocity, Usually the combination of and that results in free rolling is not known in advance. Since the steady-state transport analysis capability requires that both the rotational spinning velocity, , and the traveling ground velocity, , be prescribed, the free rolling solution must be found in an indirect manner.

One such indirect approach is illustrated in this example.

The URDFIL subroutine is used to obtain an estimate of the free rolling solution based on the values of the torque at the rim at the end of each increment. This approach is also illustrated in this example.

A nite element analysis of this problem, together with experimental results, has been published by Koishi et al. To take into account the effect of the skew symmetry of the actual tire in the dynamic analysis, the steady-state rolling analysis is performed on the full three-dimensional model, also referred to as the full model.

The paths that the material points follow through the mesh are referred to as streamlines and must be computed before a steady-state transport analysis can be performed. As discussed in Symmetric results transfer for a static tire analysis, Section 3. This option generates the three-dimensional mesh by revolving the two-dimensional tire cross-section about the symmetry axis so that the streamlines follow the mesh lines. A simple 1-term Prony series model is used. For an incompressible material a 1-term Prony series in Abaqus is dened by providing a single value for the shear relaxation modulus ratio, , and its associated relaxation time,.

Configuration of documentation application

You should not install Abaqus documentation in a directory that indicates a specific Abaqus release number. The installation procedure creates a subdirectory named Documentation under the specified directory.

During an HTML plus PDF installation, you must select one of the following options: Install and start the Abaqus web server software recommended option, to allow search functionality. In this case no search functionality is available in the HTML documentation.

Select this option if you want to view the HTML documentation from your local system without executing an active web server. Contact your system administrator or platform vendor for information on the system startup file for your computer.

This file, called the replay file, contains information that was used during the documentation installation, such as the installation directory and web server configuration. The -replay command option is available to repeat a previous installation on identical platforms without reentering the same information for each installation. You can use this option to perform a silent installation no graphical user interface is displayed. The documentation collection page index.

The documentation collection page lists the book titles grouped by category.

In the HTML documentation, each book opens in a new browser window or tab. The book window contains four HTML frames: Use the back and forward arrows in the text frame to navigate sequentially through the text. You can also use the web browser functions to return to recently viewed pages. Expand the topic headings in the table of contents by clicking the book icon to the left of the heading.

To jump directly to a section whose title is displayed in the table of contents, click that title. The abaqus doc command locates a web browser executable or the Adobe Acrobat Reader executable depending on which documentation format was installed and configured by your system administrator.

If the HTML documentation was installed and configured by your system administrator, the abaqus doc command will locate a web browser executable as follows: Windows platforms:The installation guide SimuliaInstallationGuide.

Dear Sprunger, Thanks for your information regarding abaqus software. The gures compare the solutions obtained for a tire rolling on a at rigid surface with those for a tire in contact with a rotating drum.
