In this paper, the dynamic behavior of the "car + seat + mannequin" system was explored when a car was blasted on a high-explosive munition. The motion of all elements of the dynamic system was modeled in three-dimensional space, taking into account the nonlinear characteristics of the interaction. Variants of detonation of various charges under the front wheel and under the bottom of the car, as well as options in the absence and presence of seat belts and an energy-absorbing element under the seat were considered. In the course of the study, the stresses occurring in various parts of the body and the limiting conditions of survival were determined.
