“…In this circumstance, FEA encounters difficulties due to the required computation load. To overcome this disadvantage, Wang et al [24] proposed a substructure method to analyze the power flow, where the complex system is divided into many substructures and the dynamic responses of the structure are obtained efficiently by analytical methods.…”

A power flow analysis based on a substructure approach is performed to exhibit vibration transmission in a complex coupled beam-cylindrical shell system. The system is divided into a shell substructure and a beam substructure, which are coupled by three spring-dampers. The theoretical receptance function of each substructure with a free-free interface condition is formulated by modal analysis to describe the dynamical behavior. On the basis of the receptance functions of the two substructures as well as synthesis through the geometrical compatibility and force balance conditions at the coupling interfaces, the dynamic characteristics of the coupled system are calculated. Both the input and transmitted powers within the system are estimated, and the influences of the excitation locations, the stiffness and loss factor of the spring-dampers on the vibration transmission are investigated as well.

An analytical study on the vibration and energy flow behaviors of a coupled cylindrical shell-plate structure is presented. An analytical model capable of handling general boundary and coupling conditions is developed in which the interactions of all internal forces and moments for both the shell and plate have been taken into account at the junction via four types of coupling springs with arbitrary stiffness and covering all the degrees of freedom, and each of the plate and shell displacement functions is expressed as the superposition of a two-dimensional Fourier series and several supplementary functions. The unknown expansions coefficients are obtained using the Rayleigh-Ritz procedure. The effectiveness and accuracy of the present solution are validated against the FEM results. The energy flow behaviors through this structure are investigated through parametric power flow and structural intensity analysis. The contribution of internal forces or moments to the power flow and the influence of key system parameters on the energy flow are analyzed numerically, including coupling locations, coupling conditions, boundary conditions, and excitation location. The results shed light on the effects of system parameters on the energy flow behaviors of the class of coupled shell-plate structure.

“…One of such methods is the power flow analysis, which uses the rate of energy flow to characterize the dynamic response of vibrating systems. Wang et al 15 applied this method to examine the power flowing in an L-shaped plate system excited by an external force.…”

This paper presents an improvement of the Rayleigh-Ritz substructure synthesis method that retains all the advantages of the more elaborate existing versions. The displacement field in each component is represented by a set of simple non-admissible shape functions (generalized coordinates). These are subject to a transformation to mixed coordinates (physical and internal). The physical coordinates are defined where necessary to impose boundary conditions and geometrical compatibility. The internal coordinates are chosen in order to optimize the condition number of the matrices involved. Such a change of coordinates makes possible the use of the convenient assembling procedure of the Finite Element Method. The procedure, done in a systematic manner, leaves no free choice to the user and leads to an optimal numerical behavior. Several examples of applications are presented.
