High Fidelity FE Dummy Models for CAE Vehicle Safety Analysis

In 2017, by contractual agreement with ATD-Models GmbH, CDH AG acquired the rights to market, distribute and support ATD Hybrid 3 dummy and finite element (FE) impactor models in North America and Japan. ATD-MODELS GmbH is a specialist in the development of high-quality FE models for vehicle safety analysis.  The company was founded in 2009 by experts with years of experience in dummy development and occupant-safety simulation. ATD-MODELS GmbH develops highly accurate FE models in close cooperation with the German and other world-wide automobile industry partners. ATD FE models are used in the virtual development process for occupant and pedestrian protection engineering calculations.

ATD MODEL of the SAE J826 H-Point-Manikin

The ATD-HPM is based on advanced modelling techniques resulting in a very realistic FE model of the SAE J826 H-Point-Manikin. The model allows users to accurately position the dummy and perform virtual crash measurements in CAE. Areas of applications include finite element simulations for seat configurations and dummy positions, for example, the back-set for whiplash. ATD-HPM FE models are available for hardware configurations with white or red pans.

Some characteristics of the ATD-HPM are:

  • A realistic implementation of the geometry and mass distribution of the hardware manikin
  • Pre-processor dialog for calibration according to the scales on the hardware
  • Detailed implementation of the setup scales, which allows easy comparisons to readings on hardware
  • Two models (dependent on hardware) are available:
    • ATD-HPM with white pans
    • ATD-HPM with red pans

ATD Models Features and Advantages

Advantages to Users:

  • Systematic title nomenclature refers to the assembly groups
  • Prefix in each title description allows a fast adjustment to the nomenclature of the load case
  • Numeration not overlapping the assembly groups
  • Advantage in pre and post processing
  • Allows selection of assembly parts and groups
  • Each assembly group close defined for itself
  • Definition regarding the master, e.g. contacts relate to the assembly group
