ABSTRACT:
In a method for simulation and assessment of the life or dynamic strength of components of a vehicle, the vehicle is subdivided into individual components and these components are modeled by means of a finite element method. The finite element models of the individual components are collated for simulation at interfaces. Externally introduced forces are measured on the vehicle, or are simulated, and the forces which occur at the interfaces or at specific points within the components are calculated in order to determine the weakest points from the dynamic strength point of view in the overall model. Elastic structures are modeled at the interfaces in order to simulate the real flexibility or the dynamic transmission response of the vehicle structure, and masses and/or stiffness data and/or elastomer bearing data for the elastic structures are taken into account in the model.
