Mobility Power Flow Analysis of Coupled Plate Structure Subjected to Mechanical

摘要

The mobility power flow approach is generalized, previously applied in thederivation of expressions for the vibrational power flow between coupled plate substructures forming an L configuration and subjected to mechanical loading. Using the generalized expressions, both point and distributed mechanical loads on one or both of the plates can be considered. The generalized approach is extended to deal with acoustic excitation of one of the plate substructures. In the case of the L-shaped plate, acoustic interaction exists between the two plates substructures due to the generation of the acoustic waves by each of the substructures. An approach to deal with this phenomena is described.
