FEM-Modeling of car components to predict crash
performance Factors influencing occupant loads
Diplomoppgave Per Olav Espegren Volkswagen AG,
Wolfsburg, Tyskland
Diploma will have four stages 1.
Validating/adjusting model behavior.
Focus-areas for more detailed model. 2.
Validating of FE-model values Include
detailed substructures. Adjust these to
main model. 3. Investigations of influences of
design parameters on occupant loads. 4.
Body design analysis. Structure modifications
to see the influence on dummy values.

FEM-Crash analysis influence of material
parameters on crash behaviour
To achieve good correlation between test results
and crash analyses, one must ensure correct
material models. Goal is to ascertain influence
of material model parameters on the FE crash
results Build a FE model based on the VW Touran
with various material models Run FE crash
analyses and analyses with various material
parameters and material models Compare FE
analyses with crash test results Analyse
influence of pre-forming (hardening) on the crash
behaviour
Diplomoppgave Jan Vegard Svendsen Volkswagen AG,
Wolfsburg, Tyskland

Numerical investigation by FEM-analysis of
metal-forming concepts for hollow gear shaft
Diplomoppgave Anders Jorfald DaimlerChrysler,
Stuttgart, Tyskland
Rotary swaging will be new way to form
gear-shaft. Gives advantages as freedom in design
of product, replaces conventional metal cutting
and saves material. Gives improved mechanical
properties, high precision and good surface
quality
