General Information

The Partnership for Dummy Technology and Biomechanics (PDB) decided to develop WorlSID finite element models for the crash codes LS-DYNA, PAMCRASH and ABAQUS. The PDB is a group established by a subset of the German Association for Automotive Research (FAT) members to work in the field of dummy technology and modelling. Within the project, DYNAmore is responsible for the development of the LS-DYNA model and for the contribution to the test definitions for the experimental database. The project was launched in 2006 and the participants of this project are:

- Audi
- Porsche
- BMW
- Volkswagen
- Daimler

 

The development and validation has been performed on different platforms. The following LS-DYNA versions have been used:                        

LS-DYNA Version Date Revision No.
971 R9.3 MPP 07/09/2018 143600 Product ID 143600
971 R9.3 MPP 07/09/2018 145252 Product ID 145252
971 R11 MPP 06/09/2020 148584 Product ID 148584

 

To offer a variety of LS-DYNA versions for the user to run the current WorldSID model, we tested the following releases with the barrier sled tests:                       

LS-DYNA Version Date Revision No. Recommended
971 R9.3 MPP 07/09/2018 143600 Product ID 143600  YES
971 R9.3 MPP 07/09/2018 145252 Product ID 145252  YES
971 R11 MPP 06/09/2020 148584 Product ID 148584  YES

 

 

With the version 7.6 of the WorldSID 50th model the following keyword files are delivered:

File name Content
worldSID50_pdb_v7.6_mm_ms_kg.key
Dummy model; the file name might vary depending on the system of units
worldSID50_pdb_v7.6_mm_ms_kg_IR-TRACC_left_v1.0.key  IR-TRACC LHD include file; the file name might vary depending on the system of units

worldSID50_pdb_v7.6_mm_ms_kg_IR-TRACC_right_v1.0.key

IR-TRACC RHD include file; the file name might vary depending on the system of units

worldSID50_pdb_v7.6_Ballast_left_v1.0.key

Ballast LHD include file
worldSID50_pdb_v7.6_Ballast_right_v1.0.key
Ballast RHD include file
worldSID50_pdb_v7.6_arm_sleeve_v2.0.key
Arm_sleeve model for ENCAP Far-Side
Psg_v2.1_...
Script to generate pre-simulation input (chapter 3.2).
wsid50_v7.6_all_units_server.asc
License file; the file can be used in different system of units
wsid50_v7.6_all_units_load_curves_work.key
Work file used for pre-processing instead of license file. The file name might vary depending on the system of units
worldSID50_pdb_v7.6_H-Point_tool.key
H-Point measurement device
worldSID50_pdb_v7.6.X_mm_ms_kg_RibEye_left_v4.0.key
RibEye LHD model; the file name might vary depending on the system of units
worldSID50_pdb_v7.6.X_mm_ms_kg_RibEye_right_v4.0.key
RibEye RHD model; the file name might vary depending on the system of units
 

 

The work file wsid50_pdb_vx.x_all_units_load_curves_work.key can be used for pre-processing the dummy.


This work file includes the same input as the encrypted license file. The only difference is the scaling of the load curves in the work file. The load curves are scaled randomly in a wrong range and they are much too soft to be used for a LS_DYNA simulation. But the file can be used to observe the quality and course of the material curves.
 
A LS-DYNA simulation in use of the work file will give wrong results and is very unstable.
