Quasi-Static Force-Moment Method

Full-Vehicle Assembly

Select the Full-Vehicle Assembly you want to analyze. The menu lists all full-vehicle assemblies currently open in your session.

Assembly Variant

Select the assembly variant you want to analyze. The menu lists all full-vehicle assembly variants of the chosen assembly.

Switches to the selected variant and adds the required testrig as needed.

Output Prefix

Enter a string that specifies the Analysis Output Name. The string can contain only alphanumeric characters and underscores (_). Adams Car appends the suffix _mmm to form the complete analysis name. For example, if you enter test_45 as the output prefix, the analysis name becomes test_45_mmm.

Solver Settings File

Select one or more files (extension .ssf) defining the solver settings to be temporarily applied for this simulation (optional).

Opens the Solver Settings File (extension .ssf) editor dialog box.

Number of Steps / Step Size / Step Frequency

Select either of the following:

Simulation Mode

Select interactive, background, graphical, files or event only.

See Mode of Simulation: Interactive, Mode of Simulation: Graphical, Mode of Simulation: Background, Mode of Simulation: Files_only, Mode of Simulation: Event_only.

Enter the name of a file that contains road data information. The tire subsystems use this information to calculate the tire/road interaction forces.

Tips on Entering File Names in Text Boxes.

Import and visualize road graphics from file.

Remove road or path graphics.

View road / path file in info window.

Edit road / path file in road builder or text editor.

Desired Velocity

Specify the velocity of the vehicle during the acceleration test. The velocity should match the units specified in the units pull-down menu. This velocity will be held constant during the quasi-static acceleration analysis.

Initial Side Slip Angle

Enter the initial value of the vehicle side-slip angle. A typical value is zero.

Final Side Slip Angle

Enter the final value of the vehicle side-slip angle.

Number of Side Slip Steps

Enter the number of side-slip steps. This value corresponds to the number of Solution Steps from the initial side-slip angle to the final side-slip angle.

For example, if you specify five solution steps, 0 degrees as the initial side-slip angle, and 10 degrees as the final angle, Adams Car performs six quasi-static analyses, corresponding to the following side slip angles: 0, 2, 4, 6, 8, and 10.

Steering Amplitude

Enter the angle amplitude of the steering wheel. The steering-wheel angle will be a sinusoidal signal with the specified amplitude.

Steering Cycle Duration

Enter the duration of each side-slip angle analysis. The sinusoidal steering-wheel signal will sweep an entire cycle within the specified duration.

Longitudinal Velocity

Specify the vehicle longitudinal velocity in the units specified in the pull-down menu to the right of the Longitudinal Velocity text box.

Gear Position

Specify the transmission gear for the analysis. The gear is held constant throughout the analysis.

Bank Angle

Enter the bank angle in degrees, with default being zero.

Create Event Log File

Select if you want Adams Car to write information about the assembled model and analysis to an Analysis Log File.

Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Adams Car displays different comments dialog boxes, depending on the entity type for which you want to record comments:

Select to display an Alignment dialog box where you can set toe, camber and caster alignment values.
