Model of structure-borne sound transmission through ship foundations / ship engine mounts

Model of structure-borne sound transmission through ship foundations:
An analytical computation model of structure-borne sound transmission through ship foundations is based on a general wave-guide method for coupled plates. The results can be applied with a mount model to determine the effects of a number of variables on the isolation efficiency of the mount/foundation systems and thereby optimise those systems.

Measurements on scaled-down foundations are currently going on in the laboratory. The model results are to be compared with those of measurements. The results achieved to date are promising.

Model of structure-borne sound transmission through ship engine mounts:
An analytical computation model of structure-borne sound transmission through ship engine mounts is based on a wave-guide method. The results can be applied with a foundation model to determine the effects of a number of variables on the isolation efficiency of the mount/foundation systems and thereby optimise those systems.

A general finite element model of the dynamic stiffness of mount has been developed. The results of the analytical wave-guide model are to be compared to those of the finite element model and to those of measurements. The results achieved to date are promising.
