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 × 106????/????????.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.
