Model order reduction for elastic multibody systems with moving loads
- In this paper we consider two different model reduction approaches for elastic multibody systems with moving loads. The first approach is based on a parametric formulation of the input and output matrices and application of parametric model reduction. In the second approach, we approximate the time-varying input matrix in a low-dimensional subspace and perform model reduction of a time-invariant system. Both approaches are compared for a thin-walled cylinder model with a rotating force.
