某大型集装箱船舵杆与舵柄连接方式研究

Research on the Connection between Tiller and Rudder of a Large Container Ship

船舶建造正趋于向大型化发展,大型船舶的配套的舵柄体量也随之增大,采购成本及其施工难度也会相应增加。目前,船舶舵柄与舵杆多采用无键油压和有键干压两种连接方式。本文分析研究舵柄与舵杆的连接方式,获得满足要求、便于施工、零件轻量化的最优连接方式,具有重要工程意义;结合船级社规范要求,以某大型集装箱船为例,在舵柄与舵杆的无键油压、有键干压两种传统的安装方式基础上,提出有键油压的第三种连接方式;将三种连接方式对比,并采用有限元方法进行强度校核,得出压入力、压入量、材料屈服强度等方面的结论,从而获得满足实船要求、便于船厂施工、舵柄轻量化的最优连接方式。

Ship construction is tending to large-scale development,the size of the supporting tiller of large ships also increases,the procurement cost and construction difficulty will also increases correspondingly.At present,the tiller and the rudder of the ship mainly adopt two connection ways:hydraulic-keyed connection and dry-keyed connection.By analyzing and studying the connection modes between tiller and rudder,this paper obtains the optimal connection mode which meets the requirements,is convenient for construction.The parts are lightweight,which has important engineering significance.Combined with the requirements of classification Society,this paper takes a large container ship as an example,and on the basis of the two traditional connection methods,puts forward the third connection method of hydraulic-keyed connection method.The three connection methods are compared in the paper,and the finite element method is used to check the strength,and the conclusions of push up load,push-up and material yield strength are obtained.In the end,an optimal connection mode which meets the requirements of real ship is obtained,which is convenient for shipyard construction.The designed tiller is lightweight.
