Abstract
This paper provides an overview of NHTSA's application of advanced analytical tools in side impact research. Finite Element (FE) approaches are highlighted as emerging simulation tools. Status of the Moving Deformable Barrier (MDB), Side Impact Dummy (SID), and passenger car FE model development efforts at NHTSA are reported. Simulated responses from these models are compared against crash test data. Use of FE models for general vehicle safety performance characterization is illustrated. Advanced lumped mass simulation models for vehicle safety performance and countermeasure characterizations are also discussed. Such models include barrier-to-car and car-to-pole impacts using rigid body dynamics and simplified lumped mass techniques in combination with FE techniques. Emphasis is placed on model development and extraction of modeling characteristics from both FE model outputs and crash tests. Future research directions are also presented
