• Abstract:
  This paper describes a finite element computer simulation of a New Car Assessment Program (NCAP) full scale crash test. The full scale test selected for this study is a 30 mph frontal impact of a 1993 Ford Taurus vehicle into a rigid flat wall. Finite element models of a Ford Taurus vehicle, a Hybrid III dummy, and a driver side airbag were combined to simulate the test. The vehicle, dummy, and airbag models are described in detail. The combined model validation against the full scale test is also presented. The combined model validation focuses on the comparison of the test and simulations in terms of crush depth in the front of the vehicle, the acceleration at different locations of the vehicle as well as the head and chest accelerations and the femur loads of the dummy. The simulation results are found to be consistent and in good agreement with the crash test data. Recommendations for further improvements of the model are also included in this paper.
