【Abstract】 This paper describes in detail the vibration reducing means adopted at the design stage of a 15000 ton general cargo ship. The after body lines are so formed as to make the wake field as uniform as possible and a well suited propeller is adopted to minimize the exciting force. In selecting the main engine, due attention is paid to the unbalanced forces and moments and the torsional vibration of the shaft. The general arrangement and hull structure are designed with the aim of reducing the vibration responses of the ship. Response check is made especially for the after end structural members and the structural details are improved. It is believed that all these measures taken will effectively reduce the vibration levels and prevent harmful effects, thus will enable the ship to have a better operating performance at sea.更多还原
