Suspension Analysis: Parallel Travel
(Standard Interface) Simulate → Suspension Analysis → Parallel Wheel Travel
Runs Wheel-Travel Analyses.
For the option: | Do the following: |
|---|---|
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 _parallel_travel to form the complete analysis name. For example, if you enter test_45 as the output prefix, the analysis name becomes test_45_parallel_travel. |
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. |
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. |
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 the suspension assembly contains tandem axles, 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. |
Travel Relative To | Select one of the following: ■Wheel Center - Represents the center of the wheel. ■Contact Patch - Represents the point of contact between the tire and the road. |
Control Mode | Specifies how the vertical displacement is controlled. ■Absolute - vertical displacement is controlled with absolute displacement value ■Relative - vertical displacement is controlled with displacement relative to the position at setup phase. |
Fixed Steer Position (optional) | Enter a real value that fixes either the rack displacement or the steering wheel, depending on the steering input mode you selected: ■If Steering Input = Length, Adams Car fixes the rack displacement to the value you specified. ■If Steering Input = Angle, Adams Car fixes the steering wheel to the value you specified. |
Steering Input | Select one of the following: ■Angle - The steering input is an angle applied to the steering wheel. ■Length - The steering input is a length travel applied to the rack. |
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: ■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. |
