State-Space Substructuring with Transmission Simulator

Book chapter, 2016

The dynamic substructuring focus group of SEM organizes sessions on experimental substructuring each IMAC conference and has been doing so for a number of years. Over the last decade, the use of so-called transmission simulators has trended within the community. Transmission simulators are well-modeled parts that fit to the interface of the substructures to be coupled to allow distributed interfaces and relaxation of the coupling conditions by the transmission simulator’s analytical modes at the cost of adding a decoupling step to the substructuring problem. In this paper, the transmission simulator concept is adapted to state-space substructuring. Experimental-analytical substructuring of the focus group benchmark structure, the Ampair A600 wind turbine, is used to verify the methodology.
