SUBSTRUCTURE METHODS IN VIBRATION

When the response of a structural system to dynamic excitation must be analyzed, a substructure coupling method (or component-mode synthesis method) is frequently employed to reduce the order of the finite elem ent model of the structure. This paper reviews procedures used to form ulate component modes for substructures and to assemble substructure m odels to form reduced-order models of the original system. A brief lit erature survey covering several applications of substructure coupling is also presented.
