Abstract

In this paper the three dimensional dynamic analysis of vehicle motions is presented on the basis of the finite element method, therefore the distribution of elasticity and mass of the chassis and vehicle body is taken into account accurately. The mode superposition method is improved on the description of large horizontal displacements (in longitudinal and lateral directions), while the effects of dampers and other structural elements with non-linear characteristics are considered by the pseudoforce method. Shear forces arising between road surface and tyres are determined by the cosine version of magic formula tyre model. Examples, relating to cornering and braking, are presented by the use of a bus finite element model containing 2294 degrees of freedom.
