系泊时船间作用力计算模型的浅水修正

Perfect the Generic Interaction Effects Model of Moored Ships in Shallow Waters

系泊船受驶过船影响,船间作用力通用计算模型在浅水中存在着较大误差,针对这种情况搜集了一些船模试验数据,对通用计算模型在浅水中的应用提出了修正方案.从修正后的结果看,修正后的通用计算模型有更高的精度,更加适合用于模拟器中船舶运动的仿真.另外,给出了系泊船受到的船间作用力峰值回归公式,研究了船间作用力在不同水深及初始横距下的变化规律.

When a moored ship passed by other ships, the genetic model of the interaction forces for the moored ship, has a obvious difference, especially in shallow waters. The purpose of this paper is to give a method to rectify the difference and improve the forecast accuracy of interaction forces. In this paper, a num- ber of ship model test data were processed, give the formular to represent the peak forces and moment values, propose amendments to the genetic model. The amended results have higher accuracy, more suitable for being used in ship motion simulator. These research has great significance for mooting safety.
