NHTSA Side and Rear Impact Barrier

This barrier model is available in:

• Shell element type (image above)
• Solid element type

The specifications used for the development of the NHTSA Side & Rear Moving Deformable Barrier have been taken from the NHTSA documents ‘Federal Motor Safety Standard, MVSS 214 – Side Impact Protection’, ‘Federal Motor Safety Standard, FMVSS 301 – Fuel System Integrity – Rear Impact Test’ and ‘National Highway Traffic Safety Administration, PART 587 – Side Impact Moving Deformable Barrier’.

The NHSTA MDB barrier is used by NHTSA in their SINCAP side and rear  impact tests and was also adopted by US-NCAP in 2012 for their side impact tests. When used in the FMVSS 301 rear impact the barrier is set 50mm lower.

Validation

The LS-DYNA model calibration has been done using the test results provided by Cellbond for four different impact conditions. The tests involve the barrier on a trolley impacting a rigid pole, a rigid wall, a rigid rear armature and a half rigid wall. The force-deflection curves (generated from model’s analyses and tests) for the barrier have been compared.

This validation work has been carried out in both SMP and MPP versions of LS-DYNA to ensure the performance and accuracy.

For Shell model: R9.3.0

For Solid model: R7.1.2
