Create/Modify Road
Adds a road assembly to your model. If your model includes tires, you must specify a road because each tire must reference a road. The road determines the surface friction, bumps, and other inputs to tires.
For the option: | Do the following: |
|---|---|
Name | Enter the name of the road to create or modify. |
Part | Enter a part, typically the ground part, to which the road belongs. Generally the road is fixed in ground but in some cases, the road may move (for example, a military vehicle driving on the deck of a warship). |
Property File | Enter the name of a road property file. The road property file determines the kind or road (smooth or rough, wet or dry). You can view the contents of the road property file using the View File button  . |
Graphics | Select On to display road graphics or select Off to hide any road graphics. You may want to hide the road graphics when you work on your model. Roads graphics are typically large and can affect operations such as fitting to view. |
Location and Orientation | |
Location | Enter a location for the road. The location determines the origin of the road and, along with the road property file, determines whether any tires referencing this road are initially contacting the road. |
Orient Using | Select a method to orient the road, either Euler Angles or Direction Vectors. The z direction of the road orientation is always vertical direction. Therefore, you should orient this axis of the road so it matches the vertical direction in your model. |
If you selected Euler Angles, the following option is available: | |
Euler Angles | Enter the euler angles (body 3,1,3) to orient the road. |
If you selected Direction Vectors, the following two options become available: | |
X Vector/ Z Vector | Enter the x- and z-direction vectors to orient the road. The x-, y-, and z-axes of the road are determine from the direction vectors as follows: ■Z = z-vector / | z-vector | ■Y = z-vector x x-vector / | z vector x x-vector | ■X = Y x Z / | Y x Z | For more information on XP-ZP method in Adams Solver, see argument XP in the MARKER statement. |
 | Select to add any comments about the variable to help you manage and identify it. See Comments. |
| Select to display the contents of the road property file in the Information window. This helps you determine what kind of road the file models. |
