Abstract

This article mainly describes vibration on new ship’s main engine foundation. The high

amplitude of vibration could damage ship’s hull structure and disturb ship’s passenger. The amplitude

can be reduced by adding damping in the main engine foundation. Thereby in this article, modelling

the matemathic equation to get the vibration response. In matemathic equation a software called

MATLAB is used to determine the best graphic response. The stiffness equivalen in the main engine

foundatioon is 1,29 × 106𝑁/𝑚𝑚.In this article use two damping variastion. The first point graphic

show the displacement of main engine foundation in the amount of 0.3 mm on time 0 sec, The second

point o graphic show the displacement of main engine foundation in the amount of 0.278 mm on time 0

sec, The third point graphic show the displacement of main engine foundation in the amount of 0.299

mm on time 0 sec.
