Outline of Final Research Achievements	The modeling of viscoelastic elements such as rubber bushes and the efficient analysis methods of multibody system including viscoelastic elements are discussed. The analysis of multibody system with viscoelastic elements tends to be unstable because those systems contain high eigenfrequency. In this study, the efficiency of multibody system analysis with viscoelastic elements described with the generalized Maxwell model are investigated.
