WorldSID 50th - The Next Generation Side Impact Dummy

Bhavik Shah, Yi Liu -- First Technology Safety Systems (FTSS)

This paper describes the key design features of the WorldSID 50th Model and also gives a brief overview on the Model  development.

WorldSID Dummy Model Development in cooperation with German Automotive Industry
Alexander Gromer, Sebastian Stahlschmidt -- DYNAmore GmbH
Peter Schuster -- Dr. Ing. h.c. F. Porsche AG


This paper describes the methodology used to develop the PDB WorldSID model. The test database generated to build and validate the model is described, as well as the design process of a new barrier shape to validate the model with respect to the new FMVSS 214 oblique pole test.
Development of the WorldSID 50th Model with the German Automotive Industry
Alexander Gromer, Sebastian Stahlschmidt, Reuben D'Souza -- DYNAmore GmbH
 
This paper describes the evoulution of version 1 in detail. It also contains a detailed description of the individual component test validation and its results.
Virtual testing developments of the LS-DYNA® WorldSID 50th dummy model
Alexander Schif, Yupeng Huang, Sebastian Stahlschmidt -- DYNAmore, an Ansys Company
 
In 2024 the European New Car Assessment Programme (Euro NCAP) Virtual Testing Crashworthiness (VTC) procedure for far-side impact is introduced. The LS-DYNA DYNAmore WorldSID 50th dummy model will be part of this procedure. Separate qualification criteria must be satisfied for the WorldSID model. They are specified in Technical Bulletin TB043-1. LS-DYNA DYNAmore WorldSID 50th version 8 will be the first model with the official certificate to satisfy all the defined criteria of TB043-1. TB043-1 includes three different stages of certification. Normative dummy requirements are checked in the first stage. Component level tests of head-neck and lumbar spine represent the second stage. The last stage includes a new full dummy sled test scenario representing the far-side load case. The dummy model must pass all three stages to be fully certificated.
Data preparation for the Euro NCAP far-side ISO/TS 18571 rating calculation with tools from the DYNAmore Eco System
Alexander Schif, Venkata Krishna, Yupeng Huang, Sebastian Stahlschmidt -- DYNAmore, an Ansys Company
 
In 2024 the Euro NCAP Virtual Testing far-side protocol was introduced with a monitoring phase. The
protocol defines all the requirements in precise detail. To obtain an assessment for the virtual testing,
the OEM needs to pass two validation load cases. The assessment is conducted using ISO/TS 18571
ratings. Euro NCAP is responsible for the ISO/TS 18571 rating calculations. The OEM must provide the
simulation and test data in a predefined ISO MME data format. If the ratings meet the defined criterion,
the virtual testing assessment is deemed successful.
This paper presents a straightforward workflow for preparing ISO MME data, illustrated by a case study
of a far-side test involving the open-source Toyota Yaris car and the DYNAmore WorldSID 50th dummy
model in LS-DYNA. The DYNAmore Eco System tool DM.binout2isomme is used to create the required
ISO MME files for sharing with Euro NCAP. Furthermore, the ISO/TS 18571 scores are calculated with
a Python script with the same procedure as defined by Euro NCAP.
