Land Transport

Land Transport Industry Area summary
Enrico Mangino, Centro Ricerche Fiat, Orbassano, Italy
This presentation contains the subjects (industry drivers and items to be improved) discussed during the first day of FENet AGM 2001 within the Land Transport industry workshop. The arguments have been divided among the four RTD areas.

Numerical Simulation as tool for development of prototypes (virtual try-out space)
Ludìk Kováø, MECAS ESI, Pilsen, Czech Republic
An overview on some recent trends and advances in virtual prototyping and crash simulation of transport vehicles is given. This overview highlights selected algorithmic solver code advances in the used simulation tools, the use and the modeling of new materials for crash energy absorption, concept car design techniques, massive parallel programming and performance gains, side impact barrier modeling, mechanical occupant surrogate modeling (dummies), biomechanical models human body, as well as extensions of crash simulation techniques to the simulation of drop tests, shock absorption, etc. The shown examples and descriptions testify the extreme progress and diversification crash simulation techniques have undergone in the past ten years.

Simulation of Flow and Sound Interactions
Hermann Landes, University of Erlangen-Nuremberg, Germany
We consider the numerical simulation of several phenomena arising from the interaction of acoustic wave propagation and fluid flow. Application examples are presented to demonstrate the validity of the simulation schemes.

QUALITY AND OPTIMIZATION OF NUMERICAL MODELS FOR INDUSTRIAL APPLICATIONS
LARDEUR Pascal, Compiègne University of Technology, Compiègne, France
The objective of this presentation is to highlight some issues in relation with the quality of numerical models for static and dynamic industrial applications. The keywords of the presentation are: adaptive modelling, adaptive meshing, error estimators, convergence, dispersion.
