General Information

Detailed finite element side impact dummy models of the USSID, EUROSID and ES-2 have been developed in cooperation with the German Association for Automotive Research (FAT) during the last 5 years. The development project for the ES-2 model was launched in 2001.The major goal of the development was to achieve a high degree of accuracy of the models, followed by 'stability' criteria in order to avoid numerical instabilities. The schedule and the focus of the development for the LS-DYNA models were mainly determined by the LS-DYNA user group within the FAT. Other participants in the project were : Audi,Autoliv,BMW,Bosch,Continental,Ford,Karmann,Keiper,Recaro,Daimler, Opel, Porsche, Siemens, TRW and Volkswagen.

 

  • ES-2 Model

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

LS-DYNA Version
Revision Nr.
Product-ID
971 R4.2.1 MPP
53450 64994
971 R5.1 MPP
64531 64638
971 R6.1.1 MPP 78769 79036

 

With the version 6.0 of the Euro-SID-2 50th model, the following keyword files are delivered.

 

File name Content
es2_v6.0_mm_ms_kg.key Dummy model, the filename may vary

depending on the unit system

es2_v6.0_nullshells.key Optional contact shells in the dummy
es2_v6.0_all_units_load_curves_work.key
Curves in dummy model for working on the model with a pre-processor
es2_vendor_a.date_license_comp_e.date.asc
License file including the tables and load curves of the model
positioning_es2_es2re_v6.0_mm_ms_kg.key
