Abstract

The paper presents an automated program written in MATLAB calculating the torque vibration of the ship dynamics. Based on the responses of the system at the extended coordinates, we can find amplifying function and its plot. From the consideration about the amplifying function and the points where the resonance can happen, the author suggests some methods to reduce the vibration such as: overcome the resonance, change the self-frequency, increase the resistance factor, equip with u dynamic damper and some other methods.
