Arup Cellbond Barrier Models
A range of robustly validated finite element models for LS-DYNA.
This barrier is suitable for China – Mobile Deformable Barrier LS-DYNA Shell Model for Side Impact.
- This barrier has been adopted by C-NCAP from 2024.
- The design is based on the China-NCAP document ‘C-NCAP Management Rules (2024 edition).
- Used for side mobile impact testing.
- Arup has a track record with over 20 years of experience in barrier development using proven modelling techniques that demonstrate robustness and fidelity.
The specification used for the deformable impact barrier in this documentation has been taken from the China-NCAP document ‘C-NCAP Management Rules (2024 edition). The SCDB barrier is used in the 2024 China New Car Assessment Programme (C-NCAP) in their Side Impact Testing Protocol.
Validation
The six honeycomb blocks have been validated in compliance to CNCAP SC-MDB specifications. As the cell size of the mesh is larger than the true one, the thickness of the honeycomb walls is not the real one, but it is calibrated against the corridors provided in the SC-MDB barrier specifications. The LS-DYNA model calibration has been done using the simulation results for a 40kph 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) for the individual block of the barrier have been compared against the corridors from the specification document. This validation work has been carried out in MPP SP versions of LS-DYNA R9.3.1, 11.2.2, and R13.1 to ensure performance and accuracy.
