Vibroacoustic subtractive modeling using a reverse condensed transfer function approach

Substructuring methods are a very common and efficient way to solve complex vibroacoustic problems. The Condensed Transfer Function (CTF) approach is substructuring method based on the concept of subsystem condensed transfer functions (corresponding admittances or impedances) that allows assembling acoustical mechanical subsystems coupled along lines surfaces. For certain practical applications, it may be more subtract decouple global system rather than different subsystems. In this paper, reverse formulation CTF proposed. This us predict behavior part larger system, from knowledge (CTFs) residual must removed. purposes validation, scattering problem rigid sphere in an infinite water domain impacted by acoustic plane wave considered. Comparisons with theoretical calculations used validate proposed permit studying its accuracy for two types condensation defining CTFs.
