Single Wheel-Travel Analysis

Suspension Assembly

Select the Suspension Assembly you want to analyze. The menu lists all suspension assemblies currently open in your session.

Assembly Variant

Select the assembly variant you want to analyze. The menu lists all suspension 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 _single_travel to form the complete Analysis name. For example, if you enter test_45 as the output prefix, the analysis name becomes test_45_single_travel.

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

Enter a value that corresponds to the number of Solution Steps from the lower bounds to the upper bounds of input.

Mode of Simulation

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

Vertical Setup Mode

Specifies the vertical control method at time=0. Vertical setup will be performed with either the wheel center height or the contact patch height moved to zero. For more information please see the tutorial Adding the vertical setup mode of Adams Car Suspension Testrig.

If suspension is built with __MDI_TASA_TESTRIG (available in Adams Car Truck plugin), then Fore Axle and Aft Axle tabs will be displayed. The following options are available:

Fore Axle

Used to define inputs for fore axle. By default, the values provided in the fields on Fore Axle tab will be applied to the fields on Aft Axle tab.

Aft Axle

Used to define inputs for aft axle. Fields on the Aft Axle tab are optional. If values are not provided, they will be inherited from the Fore Axle tab.

Bump Travel

Enter a real value that fixes the upper limit of wheel-center displacement relative to the input position. A positive value moves the wheel center upward.

Rebound Travel

Enter a real value that fixes the lower limit of wheel-center displacement relative to the input position. A positive value moves the wheel center upward.

Side

Select one of the following:

Fixed Wheel Center

Enter a real value that fixes the opposite wheel-center vertical displacement. For example, if you choose set Side to Left and enter 50 mm in this text box, Adams Car fixes the right side wheel-center vertical wheel center as 50 mm above design position, and moves the left wheel from the lower to the upper bound.

Travel Relative To

Select one of the following:

Control Mode

Specifies how the vertical displacement is controlled.

Fixed Steer Position

Enter a real value that fixes either the rack displacement or the steering wheel, depending on the selected steering input mode:

Steering Input

Select one of the following:

Coordinate System

Select one of the following:

The icon shows the difference between the vehicle and iso coordinate systems.

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:

Learn about Recording Comments.

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