Abstract
Dynamic Substructuring methods play a significant role in the analysis of complex systems and allow to assess the components individually and combine them in a modular fashion. By using compatible interfaces (through the Virtual Point Transformation), FRF-models from tests can be combined with numerically obtained FRF-models. In this paper a demonstrator structure consisting of a base-frame and several add-ons of varying complexity, both active vibration sources and passive components, is used for validation and comparison purposes. Test-based FRF models of the individual components are compared with numerically obtained results, a test-based FRF model of the full system obtained from test-based component models through substructuring is compared with numerically obtained results as well as a validation measurement on the full system. Finally, the system’s response to an active vibration input is predicted using a blocked-force characterization of the source on a test-bench.
