Coupled BE-FE Scheme for Three-Dimensional Dynamic Interaction of a Transversely Isotropic Half-Space with a Flexible Structure
The response of structures bonded to the surface of a transversely isotropic half-space (TIHS) under the effect of time-harmonic forces is investigated using a coupled FE-BE scheme. To achieve this end, a Finite Element program has been developed for frequency domain analysis of 3D structures, as the first step. The half-space underlying the structure is taken into consideration using a Boundar...
متن کاملThermoelastic Interaction in a Three-Dimensional Layered Sandwich Structure
The present article investigates the thermoelastic interaction in a three-dimensional homogeneous and isotropic sandwich structure using the dual-phase-lag (DPL) model of generalized thermoelasticity. The incorporated resulting non-dimensional coupled equations are applied to a specific problem in which a sandwich layer of unidentical homogeneous and isotropic substances is subjected to time-de...
متن کاملNoise Source Identification for Ducted Fan Systems
Understanding combustion noise source mechanisms, designing efficient acoustic liners and optimising active control algorithms for noise reduction requires the identification of the frequency and modal content of the combustion noise contribution. Coherence-based noise source identification techniques have been developed which can be used to identify the contribution of combustion noise to near...
متن کاملComparison of Nonlinear Control Designs for a Ducted Fan Model
In this paper we compare diierent nonlinear control design methods by applying them to the planar model of a ducted fan engine. Those design can be divided into two steps. The rst step requires the derivation of a Control Lyapunov Function (CLF), while the second involves using an existing CLF to generate a controller. The main premise of this paper is that by combining the best of these two ph...
متن کاملLinear Parameter-Varying Control of a Ducted Fan Engine
Parameter-dependent control techniques are applied to a thrust vectored ducted fan engine. The synthesis technique is based on the solution of Linear Matrix Inequalities and produces a controller which achieves speci ed performance against the worst-case time variation of measurable parameters entering the plant in a linear fractional manner. Thus the plant can have widely varying dynamics over...
