双尾鳍渔船船型的耐波性试验研究

AN INVESTIGATION ON THE SEAKEEPING QUALITY TEST OF A TWIN SKEG STERN FISHING BOAT

本文分析了深、浅吃水双尾鳍渔船的耐波性模型试验（试验项目包括：流线试验；静水中自由衰减试验；横摇、纵摇、升沉试验；船艏垂向加速度测定；甲板上浪试验和螺旋桨出水频率试验），与实船在不规则波中的性能预报，及具有良好耐波性的球尾渔船进行比较。结果表明：浅吃水双尾鳍渔船船型具有良好的耐波性。

This paper analyzes the results of model seakeeping quality tests of deep and shallow draft twin skeg stern fishing boats, including the tests of streamlines of free damping in still water, rolling,pitching and heaving, vertical accelerations at bow, deckwetness and propeller occurrence on the surface of water. The paper also gives predication of ship performance in irregular waves and comparison between the experimental results of varied models of bulb stern fishing boats which have good seakeeping qua...
