Suspension Analysis: Dynamic

(Standard Interface) Simulate → Suspension Analyses → Dynamic

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 _dynamic to form the complete analysis name. For example, if you enter test_45 as the output prefix, the analysis name becomes test_45_dynamic.
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.
Duration Time	Specify the amount of time over which you want the simulation to run.
Number of Steps	Enter an integer value that corresponds to the number of Solution Steps for the duration of your analysis. For example, if you specify 500 solution steps for duration of 5.0 seconds, your output step size will be 0.01 seconds.
Mode of Simulation	Select interactive, graphical, background, 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.
Coordinate System	Select one of the following: ■Vehicle - Independent tables ■ISO - Dependent or tilting tables The icon shows the difference between the vehicle and ISO coordinate systems.
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.
Jack Excitation Mode	Select displacement, velocity, acceleration or force.
RPC3 File Name	Enter RPC3 file containing road profile.
	Select to display channel information available in the specified RPC file.
Vertical Input	If Toggle button not selected then enter the runtime function expression that will define the left/right vertical jack actuator motion or force. Typically, the function expression will be a function of time, for example an impulse, a simple harmonic function or a frequency sweep. If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
Zero Offset	Select to offset the RPC3 data by subtracting the channels first date value from the array.
Cornering Force	If Toggle button not selected then enter a runtime function for the left and the right cornering force, applied at the contact patch. If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
Braking Force	If Toggle button not selected then enter a runtime function for the left and the right wheel braking force applied between the test rig table and the wheels, at the tire contact patch. Positive braking force acts in the direction of the rear of the vehicle. This is in the negative direction of the ISO/Tydex coordinate system. If Toggle button selected then enter an integer value that maps the RPC3 file channels to the desired input quantity.
Traction Force	If Toggle button not selected then enter a runtime function for the traction force, applied at the wheel center. If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
Aligning Torque	If Toggle button not selected then enter a runtime function for the left and the right aligning torques applied between ground and tire patches at the contact patches location. If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
Overturning Torque	If Toggle button not selected then enter a runtime function for the overturning torque. If Toggle button selected then enter an integer value that maps the RPC3 file channels to the desired input quantity.
Rolling Res. Torque	If Toggle button not selected then enter a runtime function for the rolling resistance torque. If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
Damage Force	If Toggle button not selected then enter a runtime function for the damage force. Adams Car applies damage forces perpendicularly to the plane containing the wheel part. They are expressed in the ISO-C (TYDEX C) axis system (for more information, see the Adams Tire online help). If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
Damage Radius	If Toggle button not selected then enter values for the left and right damage radius. The damage radius determines the position of the point of application of the damage forces: ■A damage radius of 0 corresponds to damage forces applied directly at the wheel center (therefore, at the origin of the ISO-C (TYDEX C) axis system). ■A damage radius of 100 mm corresponds to damage forces applied to a point 100 mm in the negative z direction of the ISO-C (TYDEX C) axis system. ■If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
Steering Excitation Mode	Select displacement, velocity or acceleration.
Steering RPC3 File	Enter RPC3 file for Steering input.
Steering Motion	If Toggle button not selected then enter the runtime function expression that will define the steering motion. Typically, the function expression will be a function of time, for example an impulse, a simple harmonic function or a frequency sweep. If Toggle button selected then select channel number that maps the RPC3 file channels to the desired input quantity.
	Select to use the Function Builder to define the runtime function expression for the steering input. See Function Builder for more information.
WFT Parameters File	Enter WFT Parameters file which contain WFT mass, Offset, Static Load, scaling factors and so on.
Compliance Matrix Requests	Select to include compliance matrix requests in the analysis output. These include outputs such as wheel rate, ride steer and so on. This option is valid only with the C++ Solver.
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 Request Selection dialog box where you can set request activity by selecting different options.
	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.
