ADAMS/Driveline

What's New

Auto-plugin capability

The new Plugin Manager added for the 2003 release changes how you load ADAMS/Driveline. The Plugin Manager allows you to select all of the plugins you want to load or unload at one time. You have the choice of loading plugins for just a single session or every time, automatically, at startup. You access the Plugin Manager from the Tools menu.

See the What's New for ADAMS/View or ADAMS/Car for details.

ADAMS/Driveline now a stand-alone product

For the 2003 release of MSC.ADAMS, we made ADAMS/Driveline a stand-alone product. It is no longer required to plug into ADAMS/Car Vehicle Dynamics. You may continue to use ADAMS/Driveline as a plug-in to ADAMS/Car through the ADAMS/Car Plugin Manager if you choose to model an integrated suspension and powertrain system.

As part of the installation of ADAMS/Driveline, a desktop shortcut icon can be selected for faster access to launch the product. You may also start ADAMS/Driveline from the Program Files menu on Windows or the MSC.ADAMS toolbar on UNIX.

New components for creating automatic transmissions

New components have been added to ADAMS/Driveline to assist in the modeling of automatic trasmissions. The following parts have been added to the Driveline Components list in the Template Builder:

Planetary Gear
Ravigneaux Gear
Conceptual Wet Clutch
Torque Converter

For more information about these components, see Introducing the Components in the ADAMS/Driveline online help.

New frequency-dependent bushing element

A new frequency-dependent bushing element has been added to this release of ADAMS/Driveline. The bushing formulation is based on a transfer function for use in the x, y, and z directions (which gives the frequency-dependent behavior) and that multiplies a linear stiffness. The nonlinear terms can be defined with an additional spline. The transfer function can be (de)activated in one, two, or three directions.

Changes

IC motion

As part of the ADAMS/Car-ADAMS/Driveline-ADAMS/Engine Functional Digital Vehicle project, we have made common the IC motion logic between ADAMS/Driveline and ADAMS/Engine. This means that now ADAMS/Engine and ADAMS/Driveline models can work using the same ADAMS/Solver functions, so they can be assembled together and simulated.

The differences, with respect to the previous version, are that now the IC motions used by ADAMS/Solver are active in the interface as well. Therefore, it is easier to understand the model configuration needed to correctly set up the initial velocity.

New shared database name

As part of the ADAMS/Car-ADAMS/Driveline-ADAMS/Engine Functional Digital Vehicle project, we have standardized the shared database names for all three products:

acar_shared
adriveline_shared
aengine_shared

You will notice changes in the templates and subsystems that reference the shared databases.

Issues resolved

36933
The IC Motions Activity dialog box of the Standard Interface showed IC motion names incorrectly. This has been fixed.

38210
Churning drag and clutch connector requests were not consistent with the other elements. The SFORCE output in the request is multiplied by -1. This has been fixed.

37851
The gear-force pressure angle was not correctly written in the .adm file (a radians to degree factor was missing). This has been fixed.

37349
Error issued when generating a gear force in ADAMS/Driveline. This has been fixed.
