一种船舶快速性能评价方法

An Evaluation Method of Ship Resistance Performance

为合理、统一地评价船舶的快速性能,基于当前的行业标准,提出一种比以往更细致的方法。以散货船、集装箱船和油船等常规主力船型为研究对象,基于上海船舶运输科学研究所试验数据库,借鉴海军系数的概念,统计分析近年来船舶快速性指标的分布情况并进行等级划分。在此基础上,建立根据主机功率、航速和排水体积评价船舶性能的实用方法。以一艘实船为例,说明评价的过程和结果,为制定相关行业标准提供参考。

The concept of admiralty coefficient is introduced into the statistical analysis of the ship data recorded in the ship database of Shanghai Ship and Shipping Research Institute,with focusing on bulk carriers,container ships and oil tankers.The distribution of resistance performance of the ships is studied and graded.A practical method is devised for evaluating the performance of a ship according to its main engine power,speed and displacement.The process of evaluation is demonstrated with an example.
