Power flow analysis of engineering structures using substructure techniques
Power flow analysis of engineering structures using substructure techniques
The general substructure receptance approach is extended and used to investigate the power flow characteristics applicable to engineering structures. This is achieved by complementing the normal dynamic equations with geometrical compatibility conditions allowing the assessment of dynamic characteristics of power flow excited and transmitted within the system. Each substructure is modelled analytically or numerically and its receptance function if formulated by modal analysis. The method may be classified as a form of substructuring analysis using a free-free interface condition. The displacement components induced by external forces and the interface coupling forces are deducted, permitting determination of the coupling forces and power flow between the interface of substructures. A power flow density vector is defined. The numerical examples demonstrate the applicability of the method and the detailed configurations display the power flow characteristics associated with beam frames, L-shaped plates, corner plates, beam-stiffened plates and coupled plate-cylindrical shell systems.

Abstract
The general substructure receptance approach is extended and used to investigate the power flow characteristics applicable to engineering structures. This is achieved by complementing the normal dynamic equations with geometrical compatibility conditions allowing the assessment of dynamic characteristics of power flow excited and transmitted within the system. Each substructure is modelled analytically or numerically and its receptance function if formulated by modal analysis. The method may be classified as a form of substructuring analysis using a free-free interface condition. The displacement components induced by external forces and the interface coupling forces are deducted, permitting determination of the coupling forces and power flow between the interface of substructures. A power flow density vector is defined. The numerical examples demonstrate the applicability of the method and the detailed configurations display the power flow characteristics associated with beam frames, L-shaped plates, corner plates, beam-stiffened plates and coupled plate-cylindrical shell systems.
