Considering the specific case of the multibody modelling of a racing motorbike; where the rigid model of the rear swingarm has been replaced with a flexible one; a general approach to flexible multibody systems modelling in Modelica is presented in this paper. In particular; the steps required to generate the model of a flexible body starting from a FEM analysis; performed with commercial packages; are detailed. Simulations results are shown with reference to a sudden braking and to a series of impacts with curbs. In this last case; an unstable behavior occurred when considering the flexible component; which is currently under investigation.
