SOLLUTIONS TO CONTROL VIBRATION OF MARINE VESSEL DURING DESIGNING AND BUILDING

Abstract

Today the ships tend to increase in size and speed, so the vibration of the ship has become a big problem when designing and building the ships. Excessive vibration must be reduced to provide comfortable for seaferers. In addition to negative impacts on people, excessive vibration can lead to damage to the structure of the ship or the failure of machinery and equipment. The paper proposes some solutions to avoid excessive ship vibration when designing ships. If simple processes are well adhered in design stage, it will avoid the big repair at the next stage duiring building the ship. Vibration analysis method based on finite element analysis process to predict vibration and evaluate the original detailed design.
