RPM-Sweep Analysis

Assembly

Select the assembly you want to analyze. The menu lists all open assemblies.

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 Driveline appends the suffix _rpm_sweep to form the complete analysis name. For example, if you enter test45 as the output prefix, the analysis name becomes test45_rpm_sweep.

End Time

Enter a number greater than zero to specify the duration of the Simulation.

Number of Steps

Enter the number of output steps in output files (.req, .gra). It affects the resolution of your animations and plots. Make sure that the number of steps you specify is high enough to display the highest frequency you want to observe.

Mode of Simulation

Select interactive, background, or files only.

See Mode of Simulation: Interactive, Mode of Simulation: Background, Mode of Simulation: Files_only.

Gear Position

Select the initial gear to be used during the simulation. Adams Driveline sets the transmission_demand in the test rig to the value you specify.

If the model you want to analyze contains gear-pair elements, then Adams Driveline engages the correct one to both the input and output shafts with kinematic joints.

RPM Start

Enter the initial value of driveline RPM. This is the RPM value of the part to which the dyno you select in the Engine Dyno text box is applied.

RPM End

Enter the final value of driveline RPM. This is the RPM value of the part to which the dyno you select in the Engine Dyno text box is applied.

Engine Dyno

Select an engine dyno you want to use to apply the correct engine rotational velocity to the model. During the analysis set-up phase, Adams Driveline sets the dyno type to motion * Velocity.

The function assigned to the motion is as follows:

Create Analysis Log File

Select if you want Adams Driveline to write information about the assembled model and simulation to a log file.

Adams Driveline names this log file after the output prefix and an output suffix, depending on the full-vehicle analysis you selected. The log file contains information about the type and success of the analysis, date and user, analysis parameters, and the active subsystem used in the simulation.

Select to display the Modify Entity Comments dialog box, where you can add multi-line comments to any entity to describe its purpose and function.

Learn about Recording Comments.

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

Friction Coeff

Select to display the Modify Friction Coefficients dialog box. If you have an assembly with rtire models, you can use the Modify Friction Coefficients dialog box to modify the friction characteristics for each tire.

For information about rtire, see Ride Wheels.
