Full-Vehicle Analysis: Suspension Parameter Measurement Machine

Full-Vehicle Assembly

Select the Full-Vehicle Assembly you want to analyze. The menu lists all compatible 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 _spmm to form the complete analysis name. For example, if you enter test_45 as the output prefix, the analysis name becomes test_45_spmm.

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.

Split Analysis

Select to create separate results and plot configuration files for each sub-events.

If you select Vertical Motion tab and Active toggle button is selected, Adams Car displays the following options:

Jounce Travel

Enter a positive real value that fixes the upper limit of body displacement relative to input position.

Rebound Travel

Enter a negative real value that fixes the lower limit of body displacement relative to the input position.

If you select Roll Motion tab and Active toggle button is selected, Adams Car displays the following options:

Roll Angle Displacement

Enter a positive real value that fixes the body roll angle displacement.

If you select Steer Motion tab and Active toggle button is selected, Adams Car displays the following options:

Steer Wheel Angle Amplitude Left

Enter a positive real value that fixes the upper displacement of steering wheel angle in left direction.

Steer Wheel Angle Amplitude Right

Enter a positive real value that fixes the upper displacement of steering wheel angle in right direction.

If you select Compliance tab and Active toggle button is selected, Adams Car displays the following options:

Force Applied At

Apply force either at Contact Patch or at Wheel Center.

When selected to Contact Patch, each force defined under compliance sub-events is applied between the test rig table and the wheel(s).

When selected to Wheel Center, each force defined under compliance sub-events is applied between test rig table and spindle.

Front Longitudinal Load

Enter values for the front left and right wheels or front single wheel that fixes the upper bound of the longitudinal force.

Rear Longitudinal Load

Enter values for the rear left and right wheels or rear single wheel that fixes the upper bound of the longitudinal force.

Front Lateral, Parallel Load

Enter values for the front left and right wheels or front single wheel that fixes the upper bound of the cornering (lateral) in-phase force.

Rear Lateral, Parallel Load

Enter values for the rear left and right wheels or rear single wheel that fixes the upper bound of the cornering (lateral) in-phase force.

Front Lateral, Opposing Load

Enter values for the front left and right wheels or front single wheel that fixes the upper bound of the cornering (lateral) out-of-phase force

Rear Lateral, Opposing Load

Enter values for the rear left and right wheels or rear single wheel that fixes the upper bound of the cornering (lateral) out-of-phase force.

Front Lateral Force Offset (Pneumatic Trail)

Enter values for front left and right wheels or front single wheel that fixes the maximum length (offset) for lateral force application

Rear Lateral Force Offset (Pneumatic Trail)

Enter values for rear left and right wheels or rear single wheel that fixes the maximum length (offset) for lateral force application

If you select Aligning Torque tab and Active toggle button is selected, Adams Car displays the following options:

Moment Applied At

Apply moment either at Contact Patch or Wheel Center

When selected to Contact Patch, each moment defined under aligning torque sub-events is applied between the test rig table and the wheel(s).

When selected to Wheel Center, each moment defined under aligning torque sub-events is applied between test rig table and spindle.

Front Parallel Aligning Moment

Enter values for the front left and right wheels or front single wheel that fixes the upper bound of the aligning in-phase torques.

Rear Parallel Aligning Moment

Enter values for the rear left and right wheels or rear single wheel that fixes the upper bound of the aligning in-phase torque.

Front Converging Aligning Moment

Enter values for the front left and right wheels or front single wheel that fixes the upper bound of the aligning out-of-phase torques.

Rear Converging Aligning Moment

Enter values for the rear left and right wheels or rear single wheel that fixes the upper bound of the aligning out-of-phase torques.

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 an Engine/Arb On/Off dialog box where you can set the engine and arb on/off option for each sub-events. See Kinematic and Compliance (Static / Dynamic) Engine / ARB Toggle Selector.

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.

Resets the dialog box to the default values.
