VDL Version 4.7

VehicleDynamics Library 4.7 is part of Modelon���s 2025.May release.

Improvements/Changes

Improved suspension analysis

The steady state suspension analysis has been extended with more kinematic calculations. This includes for example kingpin axis and front/side view swing arms for both sides. There is a new Kinematics component that calculates and visualizes some additional properties like roll center, kingpin ground intersection and related values like scrub radius and caster trail.

This suspension analysis relies on the steady-state solver included in Modelon Impact. To run these experiments, extend from templates in Suspensions.Experiments.Templates.ExternalRigControl and use Kinematics Analysis or Compliance Analysis custom functions.

Minor Changes

Updated dependencies to Modelon Base Library 5.0 and Electrification Library 2.0

Conversion of User Libraries

No conversion from Vehicle Dynamics Library 4.6 is needed.
