Dynamic substructuring - Wikipedia

Dynamic substructuring can best be seen as a domain-independent toolset for assembly of component models, rather than a modelling method of its own. Generally, dynamic substructuring can be used for all domains that are well suited to simulate multiple input/multiple output behaviour. Five domains that are well suited for substructuring are: WebApr 25, 2024 · For the Craig-Bampton method [ 2] different reduction methods were proposed in [ 3 ], namely “Modal reduction of junction coordinates”, “Guyan reduction of junction coordinates” and “Ritz reduction of junction coordinates” (which is the most general case including the first two techniques as special cases).
