Variability in the dynamic response of connected structures – a mobility approach for point connections
Variability in the dynamic response of connected structures – a mobility approach for point connections
This paper applies a mobility method to simple and idealised structures comprising one-dimensional wave bearing systems, such as cable bundles or hydraulic pipes, connected to isotropic a plate in order to explore potential methods for coupling together uniform structures. Considering point attachments of a beam to a plate, a mobility approach has been developed and implemented to quantify and understand the significance of the dynamic properties of the attachments and the variability that might be introduced by random spacing of the attachments points, variability in the stiffness of the attachments or in the properties of the attached beam. The advantage of this mobility method lies on its analytical solution from classical Euler-Bernoulli beam and thin plate solutions. Examples of a stiff or flexible beam attached to a plate through a set of elastic springs is explored. Results show how the variability in the different parameters have effects on the subsequent structural dynamic variability in different frequency ranges of the response spectrum.

Abstract
This paper applies a mobility method to simple and idealised structures comprising one-dimensional wave bearing systems, such as cable bundles or hydraulic pipes, connected to isotropic a plate in order to explore potential methods for coupling together uniform structures. Considering point attachments of a beam to a plate, a mobility approach has been developed and implemented to quantify and understand the significance of the dynamic properties of the attachments and the variability that might be introduced by random spacing of the attachments points, variability in the stiffness of the attachments or in the properties of the attached beam. The advantage of this mobility method lies on its analytical solution from classical Euler-Bernoulli beam and thin plate solutions. Examples of a stiff or flexible beam attached to a plate through a set of elastic springs is explored. Results show how the variability in the different parameters have effects on the subsequent structural dynamic variability in different frequency ranges of the response spectrum.
