摘要：This paper aims to develop an advanced Statistical Energy Analysis (SEA) modeling procedure by removing certain main assumptions of conventional SEA theory. Rigorous expressions for SEA energy responses and parameters, e.g. coupling loss factors, of complex built-up systems are derived in terms of the local modal properties of each subsystem, irrespective the level of modal overlap and coupling strength provided that the external excitations are uncorrelated, rain-on-the-roof forcing. As a result, the conventional SEA theory may then be extended to the mid-frequency range where part of the structure may only have a few of resonant modes involved. Numerical examples are given to illustrate the validity of the approach. © 2010 IEEE.
