for frontal impact
MPDB SHELL MODEL
The MPDB shell model effectively implements the latest developments of LS-DYNA codes and provides users with a stable and targeted analysis.
- Used by BMW Group and CATARC
- According to tests conducted by CATARC, our MPDB 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 Animator4 developed by GNS supports the customer in the post-processing of the results.
Specifications
The specifications of the “Euro NCAP Mobile Progressive Deformable Barrier Face Specification” Draft Version 1.2 November 2018 TB 022, served as the basis for the development of our Mobile Offset Progressive Deformable Frontal Impact Barrier (MPDB). The MPDB will be used in the 2020 European New Car Assessment Program (EuroNCAP) and, in the future, in the Chinese CNCAP from 2022 in their frontal impact test protocol.

Validation
The test results on four different impact conditions – the car fitted with a barrier hits a quarter-wall, a vertical, a rounded and a tubular impactor (specified by Euro NCAP) – form the basis for finetuning the LS-DYNA model. In addition to comparing the deflection curves (generated from analyses and tests), material tests were performed to create the material models for the distinct parts of the barrier.
