中文摘要	文章认为在船尾型线设计中若不考虑横剖线的UV度、各水线去流角大小等对船体振动的不利影响,很可能会导致艉部水流异常;螺旋桨盘面处非定常及分布不均匀的艉流将直接导致船体剧烈振动.针对发生了该类有害振动的船舶,介绍一种安装于船尾的垂向整流鳍.通过引用水动力不平衡导致螺旋桨激振力产生的基本原理,探讨垂向整流鳍整流使螺旋桨盘面处原艉流场发生有利改变的实质,揭示船尾桨前垂向整流鳍的减振机理.以实例说明该整流鳍在消除该类振动方面的突出效果.; This paper posits that the flow at stern will be unusual if designing stern lines without considering of U or V of body lines and exit angle of water lines;random flow around screw will directly make the ship vibrate hard. To these ships which have happened hard vibration, a vertical commutating fin fixed at stern is introduced. By quoting the basic theory that dynamic unbalance makes the screw vibrate, this paper discuses the fact that the vertical commutating fin changes the flow field at stern, presents the mechanism about the vertical commutating fin before screw at stern for reducing vibration. A sample illustrates the obvious effects.; 【作者单位】集美大学轮机工程学院；集美大学航海学院；舟山海洋渔业公司；广东渔船检验局厦门361021；厦门361021；舟山316131；广州510010；【作者英文名】LIU Qi-min1, ZHU Lan2, WANG Zheng-yao3, CHEN Fu-jun4 (1.College of Marine Engine Engineerng, Jimei University, Xiamen 361021, China;2.
