1. A method for simulation and assessment of the life or dynamic strength of components of a vehicle, said method comprising: subdividing the vehicle into individual components; modeling the individual components by means of a finite element method; collating the finite element models of the individual components for simulation at interfaces; measuring or simulating externally introduced forces measured on the vehicle; calculating the forces which occur at the interfaces or at specific points within the components, to determine weakest points from the dynamic strength point of view in the overall model; modeling elastic structures at the interfaces in order to simulate actual flexibility or the dynamic transmission response of the vehicle structure; and taking into account in the vehicle model at least one of stiffness data and elastomer bearing data for the elastic structures; wherein, the vehicle model or model element is matched to the real vehicle in a plurality of iteration steps by introducing selected external forces on both the vehicle model or model element, and the real vehicle; the forces which occur at the interfaces or at specific points within the components on the vehicle are compared by means of elastokinematic measurements for the entire vehicle model or model element; elastokinematic characteristics, including at least inward-springing characteristic, damper characteristic, and spring constant of the various elastic structures in the vehicle model or model element, are then adapted, such that behavior of the vehicle model or model element emulates the real vehicle at the interfaces or at the specific points within the components, with respect to forces/time or movement/time; and the iteration steps are repeated in order at the same time to adapt the elastokinematic characteristics optimally for a plurality of interfaces or a plurality of points within the components.
