Structural synthesis in the frequency domain: a general formulation
Abstract
Fundamental issues in frequency domain structural synthesis are
addressed. This work develops a general formulation
encompassing all prior contributions to the theory, including the
ability to directly synthesize displacements, stresses, and strains.
The theory is shown to be a highly efficient and exact means of
doing static and dynamic structural re-analysis, a capability
resulting from the unrestricted model reduction available in
frequency domain structural models. The formulation is based on
a physical coordinate transformation of the pre-synthesis
frequency response function system model and addresses
modification, coupling with and without interconnection
impedances, and constraint imposition. Additionally, the theory is
reformulated to accommodate boolean matrices which organize
the connectivity in the synthesis of complex systems.
