双声纳探头差动扫描的挂舷式船舶吃水测量方法

摘要

In view of the limitation of the existing ship's draft measurement methods.A hanging side ship method based on double sonar probe differential scanning is presented to detect the depth of ship's draft.On the basis of detailed analysis on ship's curved contour shape,use double sonar differential scanning technology,mathematical model for ship's draft measurement is set up,design a draught measurement method of ship.Through statistical analysis on 5 groups of draft measurement results,it is found that the maximum relative error is only 4.87%,and the precision is higher than the actual engineering error,which verifies the feasibility of the design scheme.%针对现有船载式船舶吃水测量方法的局限,提出了一种基于双声纳探头差动扫描的挂舷式船舶吃水测量方法.在详细分析船舶弧形轮廓外形基础上,利用双声纳探头差动扫描技术,建立测量船舶吃水量的数学模型,设计了一种船舶吃水测量方法.设计了实验方案,搭建了小比尺船模吃水深度实验系统,获取了小比尺船模吃水深度,通过对5组吃水测量结果的统计分析发现,小比尺船模吃水深度测量最大相对误差为4.87%,精度较高,满足实际工程误差要求,验证了该设计方案的可行性.
