VDL Version 4.6

VehicleDynamics Library 4.6 is part of Modelon���s 2025.1 release.

Improvements/Changes

Additional McPherson linkage topologies

The McPherson linkage templates now have the option to switch the spring mount to the body or subframe instead of the strut to enable modeling of dual path top mounts. An additional mount between the strut and the upright also enables modeling of a compliant connection between the two parts. These options are available in the McPhersonSTT1, McPhersonTT1, McPhersonFourBarSTT1 and McPhersonFourBarTT1 linkages.

Minor Changes

Some functions in the OpenCRG external code have been renamed to avoid conflicts with other code. This only affects the interface to the external code, Modelica function names remain unchanged.

Conversion of User Libraries

No conversion from Vehicle Dynamics Library 4.5 is needed.
