Arup Cellbond Barrier Models
A range of robustly validated finite element models for LS-DYNA.
AE-MDB Side Impact Barriers
This barrier model is available in:
- Shell element type
- Solid element type
- Shell element type for CNCAP2018
AE-MDB Side Impact Barrier: Shell and Solid models
The specification used for the development of these barriers has been taken from the Euro-NCAP document ‘AE-MDB Specification, Version 1.2’, dated 13th September 2023.
The AE-MDB was adopted by EuroNCAP and in 2015 replaced the Advanced-2000 barrier. It is intended to be used alongside the new WorldSID dummy. This barrier uses the same manufacturing principles as the side impact barrier Advanced-2000.
AE-MDB Side Impact Barrier: Shell CNCAP2018 model
The specification used for the development of this barrier has been taken from the CNCAP 2018 document ‘CNCAP Management Regulation 2018’ dated April 2017 and the Euro-NCAP document ‘AE-MDB Specification, Version 1.2’, dated 13th September 2023.
The CNCAP 2018 AE-MDB Side Impact Barrier is based on the Euro-NCAP AE-MDB Barrier with one main modification: 50mm increase in height.
Validation: all models
The LS-DYNA model calibration has been done using the test results provided by Cellbond for a 35kph dynamic impact against a rigid wall. The test involves the barrier on a trolley impacting a rigid wall.
The force-deflection curves (generated from model`s analyses and tests) for the individual block of the barrier have been compared. The results have also been checked against the force-deflection corridors from the specification document.
This validation work has been carried out in both SMP and MPP versions of LS-DYNA R11.2.2 and R7.1.2 to ensure the performance and accuracy.
