Uriot et al. 2015

These are simulation setups designed to replicate the sled tests carried out by Uriot et al. (2015) and Trosseille et al. (2018). The full references are provided at the end of this document.

Instructions

Follow the General Instructions for setting up your simulations. Make sure that all required outputs are available in the simulation output files (e.g. binout when using LS-Dyna) in an appropriate time frequency!

A detailed guide with illustrations is provided in the documentation.

Please report all new issues you encounter.

Acknowledgement

The sled pulses for the "rear" and "front" seat configuration were provided by Humanetics (from original files named Uriot-2015_Rear_Sled.key and Uriot-2015_Frontal_Sled.key) and are integrated into the file 03_Boundary_Condition.k in the present setup.

The seat model in the present repository (01a_Seat_semi_rigid_seat_210705.k) is based on the seat model created within the ENOP project (02_generic_seat_alr_22_210525.k). In the original file header (still preserved in the file), the contributions are summed up the following way:

  • ENOP project (seat characterization tests)
  • CEESAR and SUB BIO project (design, CAD)
  • Autoliv and CEESAR (model)

The setup has been developed by the Vehicle Safety Institute at Graz University of Technology to be HBM-neutral. This work was funded by the research project "QualiPro HBM4VT". We acknowledge the support of all sponsors:

  • DYNAmore Gesellschaft für FEM Ingenieurdienstleistungen GmbH, an Ansys Company
  • Global Human Body Models Consortium, LLC (GHBMC)
  • Humanetics
  • SAFER (represented by Autoliv Development AB and Volvo Car Corporation)
  • Toyota Motor Europe NV/SA

Special thanks to Humanetics for making the PMHS test data available and providing the sled pulses for the "rear" and "front" seat configuration.
