Structural-dynamical model

This section presents central points of the review. (Another such point presents the structural-dynamical model descrbied in Section IX.) In Sections VI and VII the model described here will be further developed. The... 

To calculate L(Z) in terms of the structural-dynamical model of water, we introduce the longitudinal and transverse dimensionless projections, q = py /p and = p /p, of a dipole-moment vector p. These projections are directed, respectively, along and across to the local symmetry axis. In our case (see Fig. 56b), the latter coincides with an equilibrium direction of the H-bond. Next, we introduce the longitudinal and transverse spectral functions as...

Adaptronics and control can be implemented at different points or subsystems. In order to evaluate possible concepts from a system point of view, an overall end to end model is established. The elements of such an integrated simulation model are shown in Fig. 5.3. In the left part the reduced structure (dynamics) model together with control laws are used for assessing the effects of active damping introduced by adaptronics as described below. The right part contains the optical submodel together with the telescope drives.

When the main information available for solving this problem is in the form of measured structural vibration response, then the problem is classified as a vibration-based SHM problem. If additional information - such as an analytical structural dynamics model - is used for its solution, then the method is classified as analytical model based, otherwise as a data based. This entry focuses in the latter case where analytical models are not available or are hard to obtain - the reader is referred to Fassois and Sakellariou (2009) and Farrar and Worden (2013) for a broader overview and details. In the context of this entry, the important - but obviously more difficult and scarcely studied - case of nonstationary random vibration is considered.
