Dynamic substructuring by imposed displacements, applied to the analysis of vehicle components 2005-01-4067

The purpose of this work is to present a methodology for the structural analysis of commercial vehicle components, through the finite element method, by considering dynamic load simulations of test track.
This methodology consists on the substructuring of complete models for the simulation of dynamic loads, by using modal superposition with the addition of static modes of the component in study.
Example cases are presented with the indication of percentage variations between dynamic stresses of the complete model and the values obtained from the isolated model. The latter is calculated with the imposition of the displacement history on the connection points with the complete model.
With this methodology one pursues the reduction of time per analysis cycle, during the development of new vehicle components.
