Full-Vehicle Analysis: Static Equilibrium

(Standard Interface) Simulate → Full-Vehicle Analysis → Static and Quasi-static Maneuvers → Static Equilibrium
Runs a Static Equilibrium analysis.
 
For the option:
Do the following:
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 _static to form the complete analysis name. For example, if you enter test_45 as the output prefix, the analysis name becomes test_45_static.
Solver Settings File
Select one or more files (extension .ssf) defining the solver settings to be temporarily applied for this simulation (optional).
Note: Solver settings files are applied in the order specified, so if multiple .ssf files contain the same solver settings, the last file in the list determines those settings.
Opens the Solver Settings File (extension .ssf) editor dialog box.
Simulation Mode
Select interactive, background, graphical, event or files only.
Static Set-Up
Select the desired static setup method to be performed. This method is used to set up the vehicle in the desired initial conditions of lateral and longitudinal accelerations. See Structure of Event Files to learn about the following options.
■None
■Normal
■Settle
■Straight
■Skidpad
Enter the name of a file that contains road data information. The tire subsystems use this information to calculate the tire/road interaction forces.
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.
Gear Position
Specify the transmission gear for the analysis. The powertrain subsystem uses this parameter that generally acts as a gain for the throttle-demand output from the cruise control.
Adams Car stores the gear ratios in the powertrain subsystem.
Note: The static equilibrium full vehicle analysis at zero velocity is performed with clutch disengaged to prevent output torque from the powertrain at engine idle speed for a specified gear other than neutral. Without clutch this can be accomplished by setting the gear to neutral.
Longitudinal Velocity
Enter the speed of the vehicle in the units specified in the pull-down menu to the right of the Longitudinal Velocity text box.
Longitudinal Acceleration
Enter the longitudinal acceleration.
Lateral Acceleration
Enter the lateral acceleration.
Acceleration Units
Select the acceleration units from the pull down menu.
Turn Direction
Select a right or a left turn.
Turn Radius
Enter the turn radius (in length units) of the skidpad on which the vehicle will perform the analysis.
Perform Linear
Select if you want to perform a linearization after each individual static equilibrium analysis. You can either include or exclude the damping by selecting the appropriate option. Linear analysis is done with the temporary constraints used for the settle solution.
Note: To remove the effect of temporary constraints on eigen values an alternate way is to add the "LIN/EIG,DAMP" command in the acf file.
Create Event Log File
Select if you want Adams Car to write information about the assembled model and analysis to an Analysis Log File.
Add Vehicle Dynamics Requests
Activates requests computing certain vehicle dynamics outputs during the full vehicle event.

Some of these additional requests are required for standard post-processing (reports and plots).
Compute Characteristic Values
Activates requests computing suspension and steering characteristics during the full vehicle event.

The additional requests are equivalent to those previously already available for suspension analysis.

See Output of Suspension Analyses in Adams Car - Running Analysis for more details.
Note: This feature is only available for C++ Solver.
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:
■If recording comments for modeling entities in Standard Interface, Adams Car displays the Entity Comments dialog box.
■If recording comments for any other entity type, Adams Car displays the Modify Comment dialog box.
Learn about Recording Comments.
Select to display an Alignment dialog box where you can set toe, camber and caster alignment values.
