FEM frequency analysis of the navigation mast of an ASD tug
Abstract
In this paper the natural frequency of the navigation mast has been calculated with the aid of the Finite Element Analysis. The calculated natural frequencies are compared to the dominant excitation frequencies. The purpose of the analysis is to have a margin of 15-20% between the natural frequency and the excitation frequencies.
