A capability for modeling and simulating frontal impact tests required by the crash sensing calibration task during the development process of a new motor vehicle is presented. The capability is applicable to the body-on-frame (BOF) vehicles such as light trucks and sport utility vehicles. Critical modeling techniques and guidelines for building a high fidelity frontal impact finite element BOF vehicle model were developed and validated using 15 full vehicle crash tests. The modeling techniques and guidelines can be used to model and simulate a suite of frontal impact sensing tests for BOF vehicles. Such a math-based capability could significantly reduce the development time and cost of a new light truck or sport utility vehicle.
