摘要
研究了船舶在风浪中航行的失速问题.提出了一种新的船舶失速函数.在该失速函数中,分别考虑了风、浪失速因子对船舶失速的影响,以改善波浪处于非充分成长状态时,船舶失速的预报能力.从而扩大了船舶失速函数的适用范围.实船统计分析结果表明,该失速函数具有较好的模拟失速预报精度,可供气象导航航线设计使用.
The problem on the ship's loss-speed in wind and waves has been studied in this pa-
per. A new function for the ship's lossspeed is put forward. In the function, the effects of
wind and waves on the ship's loss-speed are considered separately,so as to improve the pre-
diction of the ship's loss-speed when the waves are not fully developed. Therefore, the
scope of the application of the function can be extended. The results of the statistical analysis
for the real ship show that the prediction of the ship's loss-speed with the function is satis-
fying and it can be used in ship weather routing.
