Abstract

A Power Flow approach, where the vibrational Power Flow is expressed in terms of mobility functions is analytically investigated for simple connected structures. Using a Power Flow approach the global structure is divided into a series of substructures and the vibrational Power Flow between the substructures expressed in terms of input and transfer mobilities. Depending on the type and shape of the junction, line or point mobilities may be used. While in the case of point joints, the mobility functions are only functions of frequency, for line joints the mobility functions are variables of not just the frequency but also of space. In this thesis the application of the Power Flow method is first demonstrated for an L-shaped beam and the method is then extended to the application of a line junction between two plates forming an L-shaped plate. The results obtained in the two cases are compared to results obtained using Finite Element Analysis or Statistical Energy Analysis.
