Abstract

We propose two Galactic models with equal mass and characterised by anaxisymmetric bulge and a barred--rotating bulge, respectively. The orbits of the clusters will be computed in both these mass models in order to obtain an indication of the impact of a bar on the cluster orbits. The calculations will be applied to a sample of 10 globular clusters for which we have kinematical data.
