Abstract

This research details methods for deriving force-deflection model parameter estimates for frontal collision response in the context of the general multilinear formulation, which subsumes prior bilinear and saturation force models. Furthermore, a nonlinear power law force-deflection model is introduced in conjunction with methods for determining model coefficients from full-width engagement front to rigid barrier collision tests. For both families of models, methods are shown for the separate but coupled evaluation of the loading and unloading phases. The relationship between the force-deflection response and the peak force-crush response for both model families is discussed. Worked examples are shown detailing the practical implementation of the derived analytical models.
