GNS ODB
Model Description
Type: Offset Deformable Barrier (ODB)
Crash Test: 40 % Offset Frontal Impact
The specification of the ECE Regulation No. 94 (Annex 9) served as basis for the development of this barrier model. The ODB model is used for assessment of frontal impact of vehicles.
The ODB shell model effectively implements the latest developments of LS-DYNA codes and provides users with a stable and targeted analysis.
- According to tests conducted by CATARC, this barrier model has higher accuracy and more stable performance than similar products.
- Numerous dynamic tests in both the component area and the full barriers allow for consistent and finer calibration. That process goes beyond the regulated barrier control process.
- Simulations are compared with the results of real tests and evaluated.

- Adjusted block stiffnesses with prescribed performance corridor
- Validated to drop tower tests
VALIDATION
The LS-Dyna model of the ODB was created to comply the stiffness requirements described in the ECE Regulation No. 94.
Additionally, it was improved using multiple real test load cases to model phenomena of deformation and failure. Different impactors on various positions were used to refine the ODB model.
Comparing deflection curves and recognizing optical phenomena resulting from real component tests lead to an evolved ODB model, which maps excellently a real ODB barrier.
