An analysis of the calculation models applied for estimating the strength, the stiffness of the frame and the load-carrying car bodies, as well as the deformation of the body at collision of automobiles is carried out. The modeling features of the load-carrying systems of automobiles, having a spatial complex structure are presented by the finite element method at their bending and torsion, as well as at different schemes of collision.
The boundary conditions for the components' contact conditions at the change in the loads on the load-carrying systems, as well as for providing the possible folding processes of the components of shell type as a result of the body collision are modeled.
