The Offset Deformable Barrier (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, our ODB 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.
• Our many years of expertise are based on the models successfully developed in specific customer projects to date.
• Simulations are compared with the results of real tests and evaluated.
• Competent technical support is available at any time.
• The Post-Processor Animator developed by GNS supports the customer in the post-processing of the results.

Specifications

The specification of the ECE Regulation No. 94 (Annex 9) served as basis for the development of our Offset Deformable Barrier (ODB). The ODB model is used for assessment of frontal impact of vehicles. The goal is to comply or even to exceed the requirements, described in the regulation above. Our ODB model wants to give an ideal basis for a successful development of your vehicle structures.

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 our 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.
