Occupant Safety Simulations – Dummy Models

H. Sharma (DYNAmore)

This workshop is a compact version of the original occupant protection introductory course from DYNAmore, which usually covers a variety of topics ranging from dummy models to seatbelt system to airbag modelling. However, this workshop focuses on to give a very brief overview of the most crucial aspect of an occupant safety simulation, which is – dummy models and their positioning in a crash simulation model.

The focus is particularly on the modelling techniques and the practical applications of a dummy model. The workshop is mainly aimed at beginners who want to carry out simulations in the field of occupant protection (especially for side, front, or rear crashes) with LS-DYNA. In this workshop, participants will learn the basics of dummy model design and construction, positioning using a pre-processor like PRIMER and a subsequent pre-simulation in LS-DYNA. Initial knowledge of PRIMER and LS-DYNA program is suggested, but not necessary.

This workshop addresses following topics:

  • Dummy model design and development
  • Overview of a variety of dummy models – front, side, and rear crash
  • Dummy model manufacturers and their latest models on the market
  • Available dummy models in LS-DYNA
  • Structure of a dummy model
  • Positioning and pre-simulation of a dummy model
  • Summary

Simulation Data Management with SCALE.sdm

G. Geißler, M. Liebscher, M. Thiele (SCALE)

The workshop gives an overview of the simulation data management environment SCALE.sdm. The framework consists of three modules:

--SCALE.project: Project administration, milestones, requirements, responsibilities, targets, approval,...


--SCALE.model: Model setup (CAD, mesh, simulation), version management, load cases, HPC-submit, documentation, collaboration,...


--SCALE.result: Evaluation of test and simulation results, assessment, reports, correlation, data analysis,...

The modules are known under the former names Status.E, LoCo and CAViT.

There will be a discussion on how to benefit from SCALE solutions from the perspective of a user and from the perspective of a project manager. Examples of typical CAE workflows and processes with SCALE.sdm are introduced within live demos. A lively discussion at the end of the workshop is very welcome to investigate a potential integration of SCALE.sdm software in your environment.

Investigation of process robustness in sheet forming simulation with Dynaform and LS-OPT

M. Merten, K. Liebold (DYNAmore)

This workshop shows the application of the optimization and probabilistic analysis program LS-OPT on the drawing step of a generic fender geometry simulated with LS-DYNA to judge on the robustness and reliability of the model.

Input variables of a typical sheet forming simulation that are subject to uncertainties are alternated automatically within the framework of LS-OPT based on an inherent Monte Carlo approach. Using metamodel approximations as well as classifiers to evaluate statistical results are discussed. The influence of the variation of the input variables on typical sheet forming results is investigated, e.g. thickness reduction and the Formability Index. Alternated parameters were material properties like yield and tensile strength taken from literature.
