The most widely used architecture is the modal model, an adapted version of the Atkinson and Shiffrin model ([1968], [1971]).
Based on the findings of this study, it is proposed that the dynamics of the full foil structure, including bump interaction and foil inertia, can be represented by a modal model comprising a limited number of modes.
If highly sensitive regions are excluded, this identification method for connection using FRFs gives accurate estimations and can be applied to a general structure in an easier manner than the modal model methods which require a mathematical model of the mass, damping and stiffness matrices (or natural frequencies and mode shapes).
A modal model of the coupled electromechanical structure, obtained by employing a suitable finite-element formulation together with a modal reduction, is used in the controller design.
The aim of the research described in this article is to propose a technique for curve-fitting a modal model to frequency response functions (FRFs) in order to deal with multi-input multi-output (MIMO) systems with highly coupled modes, usually encountered in vibration testing.
Its accuracy may be affected by mode truncation, errors in eigenfunctions for a modal model or errors in mass/stiffness coefficients of finite elements for a finite element model.
A modal model using linear modes of the straight clamped clamped beam with a randomized stiffness matrix is employed to characterize the linear dynamic behavior of the uncertain beams.
In previous studies, the method originally proposed by Dat and Meurzec for curve-fitting a modal model to frequency response functions has been demonstrated to be an extremely interesting means of analyzing data measured from structures which exhibit close modes and/or high level of damping i.e., high modal coupling.
A parametric modal model is developed from conservation of momentum, a second order linear distributed stator and ballistic rotor motion.
On the "modal" model, inner awareness of an experience takes the form of an integral reflexive awareness of "this very experience".
