AE-MDB Model

GNS AE-MDB Crash Barrier Model

In 2021 CDH AG acquired marketing, sales and support rights from GNS mbH to distribute the GNS FEA barrier models in America, Europe and Asia. GNS mbH is a specialist in the development of high-quality FE software solutions (e.g. GNS Animator4) and FE models for vehicle safety analysis. Since more than 20 years, GNS mbH develops highly accurate FE Crash Barrier models in close cooperation with the German and other world-wide automobile industry partners. GNS Crash Barrier FE models are used in the virtual development process for passive vehicle safety engineering calculations.

To meet the requirements of higher vehicle weights and new body shapes, the side crash barriers are also constantly being further developed by the NCAPs. Together with the far side load case, for example, the AE-MDB. This model follows the latest developments of the hardware barrier.

GNS AE-MDB barrier model according to the latest AE-MDB specification

  • Adjusted block stiff nesses with prescribed performance corridors
  • Two versions are available, considering enabled or disabled gravity in your simulation.
  • Model mass, velocity and boundary condition is adjustable by LS-Dyna *PARAMETER

AE-MDB model

Easy Adjustable

By setting *PARAMETER GNS_MASS, GNS_XVELO, GNS_FIX, the barrier model integrates perfectly in your simulation

Basic features


The barrier model was calibrated using several hardware tests with vehicle like lateral structures as impact bodies in different positions.

Basic features


Adhesive beams, gluing honey-com to cladding sheets are able to fail under according load.
