In this paper fully equipped city bus model and its correlations with experimental data is presented.This task is developed at AGH University of Science and Technology in the EU{founded project EURECA{CHASING, in which functional virtual prototyping has been applied. The model consists of multi-body suspension made in Virtual.Lab (LMS software) built from rigid elements connected with each other with kinematics joints and exible superstructure (FEM made in HypeMesh-Altair software). Multibody models are used to simulate body dynamic behaviour. To make the realistic, all board systems such as ECAS or ABS have been modelled in AMESim (LMS software). Fully equipped city bus model has been developed for the purpose of calculating kinematics of the suspension what can be use to optimize ride and handling performance. However all models are useful if they are not corresponding to reality. For this reason experiments with real city bus have been carried out. The results of correlation numerical and experimental data have been presented and some interesting consideration have been derived.
