摘要/Abstract

摘要： 螺旋桨和不同物理参数的海冰接触碰撞产生的冰载荷会对螺旋桨和推进轴系产生不同的影响,研究其对轴系的影响及轴系的响应规律可为推进轴系的设计和布置提供建议。该文基于流固耦合方法,利用ANSYS/LS-DYNA软件计算不同物理参数的海冰和螺旋桨接触碰撞时螺旋桨受到的冰载荷并分析其冰载荷的变化规律,把获取的冰载荷输入到ABQUAS,计算了对应的冰载荷下的船舶推进轴系的应力、应变值,分析了推进轴系的应力、应变值,得到推进轴系的响应规律;得出推进轴系的动态响应受冰载荷的影响较大,随着海冰径向距离的减小而增大,随海冰尺寸和速度的增大而增大,故对冰区船舶的推进装置而言,其强度有着更高的要求。

Abstract: The ice load caused by the contact between the propeller and the sea-ice with different physical parameters will have different influences on the propeller and propulsion shafting. The study of the influence of the ice load on the shafting and the response of the shafting can provide suggestions for the design and arrangement of the propulsion shafting.The ice load on the propeller caused by the contact between the propeller and different physical parameters is calculated by using ANSYS/LS-DYNA based on the fluid structure interaction method, and then the variation of the ice load is analyzed. The obtained ice load is input into ABQUAS to calculate and analyze the stress and strain of the propulsion shafting under the corresponding ice load in order to get the response of the propulsion shafting. It shows that the dynamic response of the propulsion shafting is greatly affected by the ice load, which increases with the decrease of the radial distance of the sea-ice and the increase of the size and velocity of the sea-ice. Higher strength requirements are therefore demanded for the propulsion devices of ice ships.

Key words: impact load, sea-ice parameter, ice load, propulsion shafting, dynamic response
