摘　　要：本文对某灵便型散货船的后体船形及其伴流分布作了分析研究 ,证实了该船在实船航行时因伴流峰值过大 ,分布欠佳且尾流场异常而引起螺旋桨转速不稳定及产生艉部剧烈振动。为了降低伴流峰值 ,改善其分布及艉部流场 ,在船体线型无法改动的情况下 ,设计加装了艉整流鳍 ,取得了十分明显的效果。再次证明了采用艉整流鳍是一个简便。In this paper, the analysis and research of the afterbody ship form and wake distribution of a handy size bulk carrier are carried out. The causes of the ship vibration generated by the propeller and the unstable propeller revolution are verfied. They are the higher wake peak, unfavorable wake distribution and abnormal stem florn field. In order to reduce the wake peak and to improve the wake distribution and the stern florn field, the stern fins are designed and installed on the ship. Instead of modifying the shape of the submerged afterbody of the ship, after installing the fins, the obvious positive results are obtained. So, it is proved that the installation of fins is a very effective way to improve the wake field in case of abnormalwake.
