Research on ice-breaking induced vibration characteristic of a Ship

摘要

Based on numerical simulation, this paper studies ice-breaking induced vibration characteristics of a ship under typical working conditions. Based on acoustic-structure coupling method, an ice-breaking FE model of a ship is established. Vibration of the ship under typical ice-breaking working conditions is discussed by performing the ice-breaking force in time history to the iteration area of the model. Result shows that ice-breaking force will not only yield significant global vibration, but also local vibration in the area where ice and ship hulls collapse and supper structures.
