Modal analysis of a fast patrol boat made of composite material
Modal analysis of a fast patrol boat made of composite material
The structural dynamic behaviour of a fast patrol boat is studied with two- and three-dimensional idealisations for dry hull analysis. A preliminary two-dimensional beam analysis is conducted by means of the Prohl-Myklestad method to derive a first estimate of the first four symmetric mode shapes. A more complex three-dimensional finite element model is developed in order to evaluate the modal characteristics for both symmetric and coupled anti-symmetric distortions, with the emphasis placed on the former.

Abstract
The structural dynamic behaviour of a fast patrol boat is studied with two- and three-dimensional idealisations for dry hull analysis. A preliminary two-dimensional beam analysis is conducted by means of the Prohl-Myklestad method to derive a first estimate of the first four symmetric mode shapes. A more complex three-dimensional finite element model is developed in order to evaluate the modal characteristics for both symmetric and coupled anti-symmetric distortions, with the emphasis placed on the former.
