Assessment of Side Impact Simulation Using ABAQUS/Explicit 2006-01-0315

In order to protect occupants from the risk of serious injury in event of side impact, passenger vehicles are designed to fulfil specific legislative and consumer impact test requirements. These are generally different for each of the major markets of the world. The tests use different configurations and percentile dummies (anthropomorphic test devices). Aside from the problem of finding an optimal design, the reliable evaluation of the robustness, i.e. the sensitivity of unavoidable scatter of design variables due to the structural response, is becoming increasingly important.

For this purpose simulation is a well established tool in the development process in the automotive industry. The integration of FE-dummies and restraint systems in side impact simulations enables the study of the effect of dummy loading. ABAQUS/Explicit is a promising new software package for gaining more accuracy in crashworthiness and occupant protection simulations.

After a short description of the software programs used in side impact simulations the potential of stochastic simulation for evaluating system responses to scatter and assessing the reliability of simulated results is discussed.
