Based on Aluminum Honeycomb technology, the MDB-IIHS V2 barrier (Side Impact Moving Deformable Barrier – IIHS May 2020) is an updated version of the moving deformable barrier to be used in the Insurance Institute for Highway Safety (IIHS) side impact crashworthiness evaluations 2.0 planed being introduced by 2022.
The MBD-IIHS V2 provides a measurement tool with sufficient precision to ensure repetitive and correlative results under similar test conditions and reflect adequately the protective performance of a motor vehicle or item of motor vehicle equipment with respect to human occupants. The new barrier provides a better representation of Pick-up and SUVs front design based on updated data.
The MDB-IIHS V2 barrier consists of two parts: a Main Honeycomb Block and a Bumper Honeycomb Block. The Main Honeycomb Block comprises four elements: one Upper, two Rails, and one Middle Bottom. The Bumper Honeycomb Block comprises three elements: one Middle and two Sides.

A complete testing procedure for certification of aluminum honeycomb is performed in-house according to IIHS Side Impact Crashworthiness Evaluation 2.0, Moving Deformable Barrier Specification, version 2.0 from May 2020 and in accordance with the procedure defined in NHTSA TP-214D. The aluminum honeycomb blocks are processed such that the force deflection curve when statically crushed is within the corridors defined for each block.
The MDB-IIHS V2 barrier is developed for the IIHS Side Impact Crashworthiness Evaluation Crash Test Protocol 2.0 – 2022.
The AXAC MDB-IIHS V2 side-impact Moving deformable barrier are
manufactured according to Insurance Institute for Highway Safety Moving Deformable Barrier Specification, version 2.0, May 2020 in compliance with the Side Impact Crashworthiness Evaluation Crash Test Protocol 2.0 – 2022.
