Full Vehicle MDO

This example illustrates a realistic application of Multidisciplinary Design Optimization (MDO) and concerns the coupling of the crash performance of a full vehicle with torsional stiffness and mode frequency. LS-DYNA is used for explicit crash and implicit NVH and eigenvalue simulations.

The example has been developed
within a founded project of ASC-S (Automotive Simulation Center Stuttgart,

The underlying FE-model for this study is a free Ford Taurus LS-DYNA model from the "National Crash Analysis Center" website http://www.ncac.gwu.edu/.
