Computer Crash Tests

Despite the increasing number of vehicles, road traffic is becoming safer – as a result of new technology. This year has seen a historically low number of traffic fatalities. Simulations are a decisive tool in the process of developing safe vehicles. Crash tests are expensive and time-consuming, and they are also limited by ethical boundaries. Furthermore, they can only be carried out at a later stage in the development process.

The solution to these problems is to divide the vehicle and occupants into many nodes and finite elements to enable the use of mathematical equations and numerical simulations to predict the physical behavior long before the construction of a prototype is complete.

Computer model showing a Ford Taurus in a frontal collision (made available by the NCAC). Computed using a computer cluster by SimTech. Large parts of the vehicle, for example the trunk lid, show only small deformations and can therefore be approximated using low-dimensional models
