Linear dynamics of flexible multibody systems [PDF]
Multibody System Dynamics, 2016 A new methodology to derive the linear model of flexible multibody system dynamics is presented in this paper. This approach is based on the twoport model of each body allowing the model of the whole system to be built just connecting the inputs/outputs of each body model.
